BACKGROUND
Transperineal Prostate Biopsy (TPB) is a commonly used technique for the diagnosis of prostate cancer due to growing concerns related to infectious complications associated with transrectal ultrasound-guided prostate biopsy (TRUSB). TPB is associated with an infective complication rate of near zero, however, acute urinary retention (AUR) remains the leading complication causing morbidity. Previously in TRUSB, there was weak evidence that alpha-blockers reduce AUR rates, and their usage has been extrapolated to clinical practice with TPB. This review aims to explore if there is an evidence base for using alpha-blockers to prevent AUR following TPB.
METHODS
A systematic approach was used to search Ovid Medline and Embase using keywords related to "Transperineal" and "Retention". Articles were then screened by applying inclusion and exclusion criteria to find studies that compared alpha-blocker recipients to no alpha-blocker use in the perioperative period and the subsequent effect on AUR in TPB.
RESULTS
361 records were identified in the initial search to produce 5 studies included in the final review. No randomised controlled trials (RCTs) were identified. One observational study showed a reduction in AUR rate from 12.5% to 5.3% with a single dose of tamsulosin. A previous systematic review of complications associated with prostate biopsy concluded there may be a potential benefit to alpha-blockers given in the TPB perioperative period. Three observational studies demonstrated a harmful effect related to alpha-blocker use; however, this was well explained by their clear limitations.
CONCLUSION
Based on this review and the extrapolation from TRUSB data, perioperative alpha-blockers may offer some weak benefits in preventing AUR following TPB. However, there is significant scope and need for an RCT to further develop the evidence base further given the significant gap in the literature and lack of a standard alpha blocker protocol in TPB.

Meta-Analysis Comparative Study
Despite the availability of various drugs for benign prostatic hyperplasia (BPH), alpha(α)-blockers are the preferred first-line treatment. However, there remains a scarcity of direct comparisons among various α-blockers. Therefore, this network meta-analysis (NMA) of randomized controlled trials (RCTs) aimed to evaluate the efficacy and safety of α-blockers in the management of BPH. A comprehensive electronic search covered PubMed, Embase, Ovid MEDLINE, and Cochrane Library until August 2023. The primary endpoints comprised international prostate symptom score (IPSS), maximum flow rate (Qmax), quality of life (QoL), and post-void residual volume (PVR), while treatment-emergent adverse events (TEAEs) were considered as secondary endpoints. This NMA synthesized evidence from 22 studies covering 3371 patients with six kinds of α-blockers with 12 dose categories. IPSS has been considerably improved by tamsulosin 0.4 mg, naftopidil 50 mg and silodosin 8 mg as compared to the placebo. Based on the p-score, tamsulosin 0.4 mg had the highest probability of ranking for IPSS, PVR, and Qmax, whereas doxazosin 8 mg had the highest probability of improving QoL. A total of 297 adverse events were reported among all the α-blockers, silodosin has reported a notable number of TEAEs. Current evidence supports α-blockers are effective in IPSS reduction and are considered safer. Larger sample size with long-term studies are needed to refine estimates of IPSS, QoL, PVR, and Qmax outcomes in α-blocker users.

Acquired urethral diverticula (UD) in males is an uncommon entity, and it is rarely reported after an open simple prostatectomy or transurethral resection of the prostate. Here, we report a unique case of a UD presenting after holmium laser enucleation of the prostate (HoLEP) in a 69-year-old male with a prostate of 372 g who had five episodes of urine retention over one year despite combined medical treatment with tamsulosin 0.8 mg and finasteride 5 mg. The patient also has elevated prostate-specific antigen (PSA) with five negative prostate biopsies over the last few years. The procedure lasted six hours with difficult morcellation due to beach balls that took 3.5 hours. There were no intraoperative complications. However, he continued to have mixed urine incontinence and recurrent (six) episodes of urinary tract infection (UTI) in the first postoperative year. On evaluation, his urodynamic study did not reproduce stress urinary incontinence (SUI); however, cystoscopy and retrograde urethrogram diagnosed a 6-cm UD in the bulbar penile urethra with penoscrotal mass. The patient underwent urethral diverticulectomy and urethroplasty with a buccal mucosa graft to correct the defect. Six months after his urethral reconstruction, he continued to have mixed urine incontinence needing two pads/day. Although male UD is a rare condition, our case report seeks to heighten awareness of such a potential rare complication in men with recurrent UTIs and refractory urinary incontinence after prolonged HoLEP for extremely large prostates.

INTRODUCTION
Ureteral stents-related symptoms (USRs) are the common complications of ureteral stenting. Tamsulosin a selective alpha-1 blocker and Tadalafil a PDE-5 inhibitor are one of drugs have been used for USRs relief. In this study we aimed to evaluate the effectiveness and safety of combination therapy Tamsulosin+Tadalafil for treating USRs comparing it with the efficacy of either Tamsulosin or Tadalafil monotherapies.
MATERIAL AND METHODS
279 patients with indwelled unilateral ureteral stents were randomized to Tamsulosin 0.4 mg + Tadalafil 5 mg once a day (Group 1, n = 67), Tamsulosin 0.4 mg once a day (Group 2, n = 71), Tadalafil 5 mg once a day (Group 3, n = 69) and Placebo once a day (Group 4, n = 72). USRs severity was registered and calculated by using the Ureteral Symptoms Score Questionnaire (USSQ) at the 14 day of treatment. Side-effects and total analgesic use were recorded and compared.
RESULTS
At the endpoint in patients with unilateral ureteral stents the combination therapy Tamsulosin + Tadalafil led to statistically lower intensity of urinary symptoms comparing with Tamsulosin (15.2 ±4.3 vs 21.8±3.6, p = 0.0003) or Tadalafil (15.2 ±4.3 vs 20.6 ±2.8, p = 0.0004) monotherapy. All groups of treatment demonstrated significant relief of USRs comparing with Placebo mostly beneficial in the combined therapy group. Body pain and analgesic need in Group 1 was lower than in Groups 2, 3 or 4. Side-effects were registered rarely without statistical differences in frequency between groups.
CONCLUSIONS
Combination therapy with Tamsulosin + Tadalafil is an effective and safe option that achieves the statistically more significant relief of USRs comparing with Tadalafil or Tamsulosin monotherapies.

To evaluate the optimal duration of Medical Expulsive Therapy (MET) application for distal ureteric stones on a time period based manner. 89 patients with 5-10 mm distal ureter stones received tamsulosin (0.4 mg) for MET and diclofenac sodium (75 mg) for analgesia. Patients were evaluated once a week for 4 weeks. Radiologic stone passage was evaluated by kidney ureter bladder (KUB) and ultasonography where non-contrast computed tomography (NCCT) was also performed if needed. While 23 cases (28.4%) were SF after first week, 23 were SF (28.4%) after 2 weeks, 9 cases (11.1%) after 3 and lastly 7 cases (8.6%) became SF after four weeks. Nineteen (23.5%) cases were not SF after 4 weeks. A positive relationship was found between the time period elapsed for stone passage and ureteral wall thickness (UWT) along with the degree of hydronephrosis. In addition, mean number of renal colics and emergency department (ED) visits were found to be higher in patients passing stones in the 4th week along with the ones who could not despite MET. SFR for distal ureteric stones sizing 5-10 mm was higher within the first 3 weeks under MET application. Thus, waiting for a longer period of time may result in increased analgesic and unnecessary MET treatment with increased risk of emergency department visits and additional costs as well. We believe that other options could be considered in such cases who are not SF at the end of the first 3 weeks.

Review
BACKGROUND
Small round cell tumor (SRCT) is a group of malignancy with similar optical microscopic morphology. Despite its low incidence, SRCT has a high malignant degree and poor prognosis. Besides, atypical clinical symptoms make it difficult in preoperative diagnosis.
CASE REPORT
A 67-year-old man was presented to the outpatient service with dysuria and weak urine stream lasting for 3 months. After oral treatment with tamsulosin and finasteride for 2 months, the symptoms worsen. Transurethral prostate holmium laser enucleation was operated and postoperative pathology result revealed small blue round cell malignant tumor. Further immunohistochemistry and fluorescence in situ hybridization examination indicated Ewing-like SRCT. So a Da Vinci Robotic prostatectomy was performed further and whole-genome sequencing was conducted. Several gene mutations including RAF1, ARID1A, SMARCA4, and BCL2L11 were found but no FDA-approved drug could treat specifically. Then the patient received Ewing-type therapeutic regimens treatment and has been followed up to date (over 24 months).
CONCLUSION
Because of its non-elevated serum PSA level, prostate SRCT is often ignored as a possibility of malignant tumor and regarded as benign prostatic hyperplasia (BPH). The possibility of prostate SRCT need to be considered if dysuria symptoms could not alleviate significantly after a period of oral treatment.

BACKGROUND
Managing overactive bladder (OAB) symptoms in Parkinson's disease (PD) is challenging. This study aimed to investigate the medical management of OAB symptoms in patients with PD.
METHODS
Patients with OAB symptoms who were newly treated with tolterodine and/or tamsulosin were screened from a database of 187 PD patients. Before treatment, the Hoehn-Yahr scale, International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS), and urodynamic evaluation were evaluated. On day 21 of treatment, the IPSS and OABSS were re-evaluated. The changes of these scores and urinary symptoms were analyzed.
RESULTS
Seventy patients with a mean age of 62.2±7.9 years and median Hoehn-Yahr stage of 2 (IQR 2-3) were enrolled. Tolterodine, tamsulosin, and tolterodine + tamsulosin were used in 43, 20, and 7 patients, respectively. The IPSS storage symptoms (9.4±3 . 3.5±2.3) and OABSS (9±2.8 . 4.8±3.3) improved significantly after treatment (both P<0.01). However, 28 (40%) patients displayed moderate urinary symptoms, and nocturia and urgency still affected more than half of the patients after treatment.
CONCLUSIONS
Tolterodine and/or tamsulosin can significantly improve OAB symptoms in PD patients. Nocturia and urgency remain common after treatment.

OBJECTIVES
Alpha-adrenergic antagonists are commonly used to prevent recurrent urethral obstruction in cats with mixed reports of efficacy. No published data on tamsulosin use in cats are available. The objective of this study was to measure changes in urodynamic parameters and blood pressure in five healthy male cats before and after administration of tamsulosin orally for 4 and 10 days.
METHODS
Five young healthy adult male cats from a research colony were administered tamsulosin at 0.1 mg/cat PO q24h for 10 days. Urethral pressure profile and blood pressure measurements were performed before treatment and approximately 6 h after treatment on days 4 and 10. Maximum urethral closure pressure (MUCP) for the prostatic and penile urethra, functional urethral length (FPL), functional area (FA) and systolic blood pressures were recorded and compared between the time points.
RESULTS
Significant changes in blood pressure on day 4 (121.1 mmHg ± 20.2 mmHg) and on day 10 (112.6 mmHg ± 14.9 mmHg) compared with day 0 (141.1 mmHg± 33.4 mmHg) were not detected ( = 0.18) in anesthetized cats. No significant difference in MUCP, FA or FPL measurements were detected among baseline, day 4 and day 10 of treatment. Hematuria and transient pollakiuria were induced in two cats with 3.5 Fr urethral catheters.
CONCLUSIONS AND RELEVANCE
Tamsulosin at 0.1 mg/cat PO q24h did not induce hypotension in healthy cats. Urodynamic testing performed 6 h after the tamsulosin pill was administered did not detect consistent decreases in urodynamic functions induced by tamsulosin. Repeated catheterization of tom cats with 3.5 Fr catheters may induce significant urethral trauma.

Review
RATIONALE
Eosinophilic cystitis (EC) is a rare and specific transmural inflammatory disease in clinic. At present, its etiology is unknown, its clinical manifestations are diverse, and its auxiliary examination lacks specificity, so it is easy to be missed or misdiagnosed in clinical practice.
PATIENT CONCERNS
A 72-year-old male patient with symptoms of lower urinary tract obstruction accompanied by hematuria was diagnosed with benign prostatic hyperplasia with bleeding by B-ultrasound and urinary CT examination. After being treated with catheterization, anti-infection and hemostasis, he was selectively treated with transurethral resection of prostate, but he saw a pattern mass on the right back wall of the bladder during the operation. Considering bladder tumor, he removed the lesion and gave pirarubicin for bladder perfusion. However, the postoperative pathological result was EC.
DIAGNOSIS
The diagnosis of EC can only rely on pathological examination, and the accurate and positive rate of biopsy can be improved by obtaining muscle tissue as much as possible at the same time of multi-point biopsy.
INTERVENTION
Prednisone and cetirizine were given orally after transurethral resection of lesions, and tamsulosin and finasteride were given regularly to treat benign prostatic hyperplasia.
OUTCOMES
No recurrence and abnormal urination were found during the follow-up for half a year, and the upper urinary tract function was normal.
LESSONS
The clinical manifestations of EC are atypical, the laboratory examination and imaging examination are not specific, and it is difficult to make a definite diagnosis before operation. The diagnosis depends on pathological examination. Transurethral resection of the lesion can obviously improve the positive rate of biopsy while completely removing the lesion, and the combined drug treatment can achieve satisfactory results in a short period of time. Active follow-up after operation is very important to identify the recurrence of the disease and prevent the upper urinary tract function from being damaged.

World Journal of Urology Feb 2024To evaluate the effect of semirigid ureteroscopy and tamsulosin therapy as dilatation methods before flexible ureteroscopy advancement to the renal collecting system. (Randomized Controlled Trial)
Randomized Controlled Trial
OBJECTIVE
To evaluate the effect of semirigid ureteroscopy and tamsulosin therapy as dilatation methods before flexible ureteroscopy advancement to the renal collecting system.
PATIENTS AND METHODS
This prospective study included patients with renal stones less than 2 cm who underwent retrograde flexible ureteroscopy and laser lithotripsy. The patients were randomized into two groups: group A patients were given a placebo for 1 week before flexible ureteroscopy, and group B patients were administered 0.4 mg of tamsulosin once daily for 1 week before surgery and underwent active dilatation using semirigid ureteroscopy before flexible ureteroscopy. The ability of the flexible ureteroscope to reach the collecting system in both groups during the same operative session was assessed. Operative outcomes and complications were collected and analyzed in both groups.
RESULTS
A total of 170 patients were included in our study, with each group comprising 85 patients. In group B, the flexible ureteroscope successfully accessed the kidney in 61 patients, while in group A, the flexible ureteroscope was successful only in 28 cases (71.4% versus 32.9%). In group A, 33 (38.8%) patients had lower urinary tract symptoms compared to 17 (20.2%) patients in group B (P = 0.013).
CONCLUSION
Using tamsulosin therapy and semirigid ureteroscopy as dilatation methods before flexible ureteroscopy increased the success of primary flexible ureteroscopy advancement to renal collecting system.
