Review
BACKGROUND
Testing of urine samples is noninvasive and could overcome several barriers to screening for chlamydial and gonococcal infections, but most test samples are obtained directly from the cervix or urethra.
PURPOSE
To systematically review studies that assessed the sensitivity and specificity of nucleic acid amplification tests for Chlamydia trachomatis and Neisseria gonorrhoeae in urine specimens and to compare test characteristics according to type of assay, site of sample collection, presence of symptoms, disease prevalence, and characteristics of the reference standard.
DATA SOURCES
Relevant studies in all languages were identified by searching the MEDLINE database (January 1991 to December 2004) and by hand-searching the references of identified articles and relevant journals.
STUDY SELECTION
Studies were selected that evaluated 1 of 3 commercially available nucleic acid amplification tests, included data from tests of both a urine sample and a traditional sample (obtained from the cervix or urethra), and used an appropriate reference standard.
DATA EXTRACTION
From 29 eligible studies, 2 investigators independently abstracted data on sample characteristics, reference standard, sensitivity, and specificity.
DATA SYNTHESIS
Articles were assessed qualitatively and quantitatively. Summary estimates for men and women were calculated separately for chlamydial and gonococcal infections and were stratified by assay and presence of symptoms. The pooled study specificities of each of the 3 assays exceeded 97% when urine samples were tested, for both chlamydial infection and gonorrhea and in both men and women. The pooled study sensitivities for the polymerase chain reaction, transcription-mediated amplification, and strand displacement amplification assays, respectively, were 83.3%, 92.5%, and 79.9% for chlamydial infections in women; 84.0%, 87.7%, and 93.1% for chlamydial infections in men; and 55.6%, 91.3%, and 84.9% for gonococcal infections in women. The pooled specificity of polymerase chain reaction to gonococcal infections in men was 90.4%. In subgroup analyses, the sensitivity did not vary according to the prevalence of infection or the presence of symptoms but did vary according to the reference standard used.
LIMITATIONS
Few published studies present data on the transcription-mediated amplification or strand displacement amplification assays, and few studies report data from asymptomatic patients or low-prevalence groups.
CONCLUSIONS
Results of nucleic acid amplification tests for C. trachomatis on urine samples are nearly identical to those obtained on samples collected directly from the cervix or urethra. Although all 3 assays can also be used to test for N. gonorrhoeae, the sensitivity of the polymerase chain reaction assay in women is too low to recommend its routine use to test for gonorrhea in urine specimens.

BACKGROUND
Tissue expansion is a versatile reconstructive technique providing well-vascularized local tissue. The current literature focuses largely on tissue expansion for breast reconstruction and in the context of burn and pediatric skin/soft tissue replacement; however, less traditional applications are also prevalent. The aim of this study was to systematically review the utilization of tissue expansion in such less well-characterized circumstances.
METHODS
The authors conducted a systematic review of all publications describing non-breast applications of tissue expansion. Variables regarding expander specifications, expansion process, and complications were collected and further analyzed.
RESULTS
A total of 565 publications were identified. Of these, 166 publications described tissue expansion for "less traditional" indications, which fell into 5 categories: ear reconstruction, cranioplasty, abdominal wall reconstruction, orthopedic procedures, and genital (penile/scrotal and vaginal/vulva) reconstruction. While lower extremity expansion is known to have high complication rates, tissue expander failure, infection, and exposure rates were in fact highest for penile/scrotal (failure: 18.5%; infection: 15.5%; exposure: 12.5%) and vaginal/vulva (failure: 20.6%; infection: 10.3%; exposure: 6.9%) reconstruction.
CONCLUSIONS
Tissue expansion enables index operations by providing additional skin before definitive reconstruction. Tissue expanders are a valuable option along the reconstructive ladder because they obviate the need for free tissue transfer. Although tissue expansion comes with inherent risk, aggregate outcome failures of the final reconstruction are similar to published rates of complications without pre-expansion. Thus, although tissue expansion requires a staged approach, it remains a valuable option in facilitating a variety of reconstructive procedures.

Comparative Study Meta-Analysis Review
OBJECTIVE
Suprapubic catheterization is commonly used for postoperative bladder drainage after gynecologic procedures. However, recent studies have suggested an increased rate of complications compared with urethral catheterization. We undertook a systematic review and meta-analysis of randomized controlled trials comparing suprapubic catheterization and urethral catheterization in gynecologic populations.
DATA SOURCES
PubMed, EMBASE, CINAHL, Google Scholar, and trial registries were searched from 1966 to March 2012 for eligible randomized controlled trials comparing postoperative suprapubic catheterization and urethral catheterization in gynecologic patients. We used these search terms: "catheter," "supra(-)pubic catheter," "urinary catheter," "gyn(a)ecological," "catheterization techniques gyn(a)ecological surgery," "transurethral catheter," and "bladder drainage." No language restrictions were applied. METHODS AND STUDY SELECTION: The primary outcome was urinary tract infection. Secondary outcomes were the need for recatheterization, duration of catheterization, catheter-related complications, and duration of hospital stay. Pooled effect size estimates were calculated using the random effects model from DerSimonian and Laird.
TABULATION, INTEGRATION, AND RESULTS
In total, 12 eligible randomized controlled trials were included in the analysis (N=1,300 patients). Suprapubic catheterization was associated with a significant reduction in postoperative urinary tract infections (20% compared with 31%, pooled odds ratio [OR] 0.31, 95% confidence interval [CI] 0.185-0.512, P<.01) but an increased risk of complications (29% compared with 11%, pooled OR 4.14, 95% CI 1.327-12.9, P=.01). Complications were mostly related to catheter tube malfunction with no visceral injuries reported. No differences in the rate of recatheterization or hospital stay were demonstrated. Robust patient satisfaction and cost-effectiveness data are lacking.
CONCLUSION
Based on the best available evidence, no route for bladder drainage in gynecologic patients is clearly superior. The reduced rate of infective morbidity with suprapubic catheterization is offset by a higher rate of catheter-related complications and crucially does not translate into reduced hospital stay. As yet, there are insufficient data to determine which route is most appropriate for catheterization; therefore, cost and patient-specific factors should be paramount in the decision. Minimally invasive surgery may alter the requirement for prolonged postoperative catheterization.

Meta-Analysis
Background: Human papillomavirus (HPV) infection is associated with cervical cancer; however, it is controversial whether it is involved in non-cervical genital cancers. Objective: This study aimed to evaluate articles on the prevalence of HPV in penile cancer, vulvar cancer, colorectal cancer, prostate cancer and anal canal cancer in studies conducted in Brazil. Methods: The study was conducted in accordance with the Preferred Reporting of Systematic Reviews and Meta-Analysis Statement. Comprehensive searches for HPV and cancer for the years 2006 to 2016 were conducted in two databases (PubMed and Web of Knowledge) and Google Scholar system. We also tracked the references of all eligible articles to identify additional non-captured publications through online surveys. Results: Eighteen studies, with a combined sample size of 1,552 patients were analyzed. The overall prevalence of HPV was 43% (95% CI: 36–51%; p < 0.001). The pooled prevalence of HPV in penile cancer was 42% (95% CI: 32–55%; p < 0.001), in colorectal cancer it was 67% (95% CI: 64–70%; p < 0.001) and in vulvar cancer 43% (95% CI: 34–55%; p < 0.001). HPV 16 was the most prevalent in all sites evaluated, with prevalence estimated at 54% (95% CI: 44–66%; p < 0.001), followed by genotypes 33 (21%; 95% CI: 17–28; p < 0.001), 6 (15%; 95% CI: 8–26%; p < 0.001), 11 (13%; 95% CI: 5–32%; p < 0.001) and 18 (12%; 95% CI: 7–22%; p < 0.001), respectively. The pooled prevalence of single infection was 82% and infection by multiple genotypes of HPV was 22%. Conclusion: Our study demonstrated a high prevalence of HPV in non-cervical genital cancers in Brazil, with predominance of genotype 16, providing evidence for the need for preventive and control measures to avoid future harm to the population.

Review
Most cancers are related to lifestyle and environmental risk factors, including smoking, alcohol consumption, dietary habits, and environment (occupational exposures). A growing interest in the association between sexual activity (SA) and the development of different types of tumors in both men and women has been recorded in recent years. The aim of the present systematic review is to describe and critically discuss the current evidence regarding the association between SA and male genital cancers (prostatic, penile, and testicular), and to analyze the different theories and biological mechanisms reported in the literature. A comprehensive bibliographic search in the MEDLINE, Scopus, and Web of Science databases was performed in July 2021. Papers in the English language without chronological restrictions were selected. Retrospective and prospective primary clinical studies, in addition to previous systematic reviews and meta-analyses, were included. A total of 19 studies, including 953,704 patients were selected. Case reports, conference abstracts, and editorial comments were excluded. Men with more than 20 sexual partners in their lifetime, and those reporting more than 21 ejaculations per month, reported a decreased risk of overall and less aggressive prostate cancer (PCa). About 40% of penile cancers (PCs) were HPV-associated, with HPV 16 being the dominant genotype. Data regarding the risk of HPV in circumcised patients are conflicting, although circumcision appears to have a protective role against PC. Viral infections and epididymo-orchitis are among the main sex-related risk factors studied for testicular cancer (TC); however, data in the literature are limited. Testicular trauma can allow the identification of pre-existing TC. SA is closely associated with the development of PC through high-risk HPV transmission; in this context, phimosis appears to be a favoring factor. Sexual behaviors appear to play a significant role in PCa pathogenesis, probably through inflammatory mechanisms; however, protective sexual habits have also been described. A direct correlation between SA and TC has not yet been proven, although infections remain the most studied sex-related factor.

Review
BACKGROUND
Groin dissection is commonly performed for the treatment of a variety of cancers, including melanoma, and squamous cell carcinoma of the skin, penis or vulva. It is uncertain whether insertion of a drain reduces complication rates, and, if used, the optimum time for drain removal after surgery is also unknown.
OBJECTIVES
To assess the current level of evidence to determine whether placement of a drain is beneficial after groin dissection in terms of reducing seroma, haematoma, wound dehiscence and wound infection rates, and to determine the optimal type and duration of drainage following groin dissection if it is shown to be beneficial.
SEARCH METHODS
In September 2014 we searched the following electronic databases using a pre-designed search strategy: the Cochrane Wounds Group Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library). In November 2013 we searched Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE and EBSCO CINAHL. We did not restrict the search and study selection with respect to language, date of publication or study setting.
SELECTION CRITERIA
We considered all randomised controlled trials (RCTs) comparing wound drainage with no wound drainage in individuals undergoing groin dissection, where the most superior node excised was Cloquet's node (the most superior inguinal lymph node). No limits were applied to language of publication or trial location. Two review authors independently determined the eligibility of each trial.
DATA COLLECTION AND ANALYSIS
Two review authors, working independently, screened studies identified from the search; there were no disagreements.
MAIN RESULTS
We did not identify any RCTs that met the inclusion criteria for the review.
AUTHORS' CONCLUSIONS
There is a need for high quality RCTs to guide clinical practice in this under-researched area.

Review
OBJECTIVES
Complete primary repair of exstrophy (CPRE) was established as a method to reduce numbers of procedures for the reconstruction of bladder exstrophy (BE). Performed since 1989, some suggest it as a replacement for the staged reconstructive procedure, the gold standard. Does CPRE reduce the numbers of procedures for reconstruction of BE?
METHODS
Literature was reviewed from 1989 to 2016, and articles evaluating outcomes of patients undergoing CPRE, extracted. Effort was made to obtain final data from each reporting institution/group. Eleven articles meeting criteria were evaluated for qualitative systematic review. Age at initial closure, complications, additional procedures, and outcomes were evaluated to provide an overview of CPRE.
RESULTS
Ten groups reported BE management using the CPRE technique. 236 patients (153 boys; 72 girls; 11 unknown sex) had primary closure ranging from birth to 5.6 years. Osteotomy was favored by most in infants closed beyond the first 72 h of life along with spica cast immobilization. Three groups recommended concomitant augmentation for infants with small bladder capacities. Ureteral reimplantation was required in 58 patients with recurrent urinary tract infections resistant to prophylaxis. Hypospadias repair was required for most boys having complete penile disassembly, and most children eventually required bladder neck reconstruction (BNR) for continence. Overall, voiding without BNR was noted in 16-37% of children in the reported series.
CONCLUSIONS
Complete primary repair of exstrophy has been suggested as a single procedure for the management of BE. Literature review suggests most patients require multiple procedures to complete reconstruction and attain continence.

Comparative Study Meta-Analysis Review
BACKGROUND
Cryotherapy is one of the most commonly used therapeutic modalities to treat anogenital warts (AGWs), but this treatment was not clearly established in the recent international recommendations.
OBJECTIVE
To compare the efficacy and safety of cryotherapy versus other AGW treatments.
METHODS
Through a systematic search of 12 electronic databases, we identified 11 randomized controlled trials, screened from database inception through October 2016, that met the inclusion criteria (including immunocompetent adults with AGWs receiving cryotherapy in 1 of the comparison groups). Primary endpoint was complete clearance of AGW. Risk-for-bias assessment was based on Cochrane Handbook recommendations. Meta-analyses used Review Manager v5.3 software.
RESULTS
Cryotherapy efficacy did not appear to differ from that of trichloroacetic acid, podophyllin, or imiquimod. Electrosurgery was weakly associated with better AGW clearance than cryotherapy (risk ratio [RR] 0.80, 95% confidence interval [CI] 0.65-0.99). Cryotherapy was associated with more immediate low-level adverse events (erythema, stinging, or irritation; RR 3.02, 95% CI 1.38-6.61) and immediate pain requiring oral analgesics (RR 2.11, 95% CI 1.07-4.17) but fewer erosions (RR 0.57, 95% CI 0.36-0.90).
LIMITATIONS
All but 1 randomized-controlled trial had a high risk for bias.
CONCLUSION
With low-level quality of the evidence, cryotherapy is an acceptable first-line therapy to treat AGWs.

Review
To evaluate the efficacy and safety of different bulking agents for treating urinary incontinence in women, a systematic review including only randomized controlled trials was performed. The subjects were women with urinary incontinence. The primary outcomes were clinical and urodynamic parameters. The results were presented as a weighted mean difference for non-continuous variables and as relative risk for continuous variables, both with 95% confidence intervals. Initially, 942 studies were identified. However, only fourteen eligible trials fulfilled the prerequisites. Altogether, the review included 1814 patients in trials of eight different types of bulking agents, and all studies were described and analyzed. The measured outcomes were evaluated using a large variety of instruments. The most common complications of the bulking agents were urinary retention and urinary tract infection. Additionally, there were certain major complications, such as one case of death after use of autologous fat. However, the lack of adequate studies, the heterogeneous populations studied, the wide variety of materials used and the lack of long-term follow-up limit guidance of practice. To determine which substance is the most suitable, there is a need for more randomized clinical trials that compare existing bulking agents based on standardized clinical outcomes.

CONTEXT
Penile prosthesis surgery is currently the most effective treatment for erectile dysfunction when medical treatment is ineffective or contraindicated. Among the surgical approaches described in the literature, the scrotal, infrapubic and subcoronal are the most common in the daily clinical practice.
OBJECTIVES
The main objectives were to describe the infrapubic surgical technique evaluating its indications and complications, as well as comparing its advantages and disadvantages with the penoscrotal approach.
ACQUISITION AND SYNTHESIS OF THE EVIDENCE
A literature review from 1983 until current date was carried out in Medline (PubMed and Cochrane Library databases) following PRISMA standards. Sixteen studies were included: 4 prospective, 4 retrospective, one systematic review, one randomized trial, one original article, 5 expert opinion/surgical technique descriptive paper.
DISCUSSION
According to the literature reviewed, although the penoscrotal approach is the most applied, the infrapubic approach showed a shorter operative time and a tendency for an earlier recovery of sexual activity after surgery. Complications are rare, having similar rates to the penoscrotal approach; no cases of glans hypoesthesia have been reported and peri-prosthetic infection rates were less than 3%. Satisfaction rates of infrapubic penile prosthesis were higher than 80%.
CONCLUSIONS
Penile prosthesis implantation requires of a profound knowledge of the different surgical approaches in order to best adapt each technique based on each individualized case. The infrapubic approach, even if it is not the most used, is as feasible and reliable as the penoscrotal approach. The infrapubic approach is effective and safe, with high level of both, patients and partners' satisfaction.
