PURPOSE
To evaluate if preoperative sterile pyuria can be a prognostic factor for intravesical recurrence (IVR) and overall survival (OS)in patients with upper tract urothelial carcinoma (UTUC) undergoing surgery.
MATERIALS AND METHODS
We retrospectively reviewed the medical records of patients who were diagnosed with UTUC from October 2003 to December 2016 at Korea University Medical Center. Sterile pyuria was defined as urine containing five or more white blood cells per high-power field in the absence of bacteria in urine culture. We used a stepwise multivariable Cox proportional hazards model to assess the independent effects of the prognostic factors for IVR and OS.
RESULTS
We investigated a total of 176 patients who were diagnosed with UTUC. Among them, 91 (51.7%) patients had preoperative sterile pyuria. There were no significant differences in the baseline characteristics between the pyuria and non-pyuria groups concerning tumor grade, T stage, tumor multiplicity, and recurrence history. However, there was a significant difference in the IVR between the two groups. In the multivariable analysis, preoperative sterile pyuria, diabetes mellitus, high-grade tumor, and lymphovascular invasion were revealed as independent risk factors for IVR, and only lymphovascular invasion was identified as an independent risk factor for OS.
CONCLUSIONS
Preoperative sterile pyuria is significantly associated with IVR in patients with UTUC undergoing surgery, but it is not associated with OS. Furthermore, diabetes mellitus, high-grade tumor, and lymphovascular invasion are also independent prognostic factors for these patients.

INTRODUCTION
The effect of repeated cystoscopy on bladder cancer (BC) patient anxiety and feelings is rarely evaluated.
AIM
To compare the difference of patients' anxiety and subjective feelings caused by different cystoscopes.
MATERIAL AND METHODS
We prospectively included 192 BC patients who accepted regular cystoscopy follow-up after transurethral resection of bladder tumor (TURBT): 93 in the flexible group and 99 in the rigid group. The method of anesthesia and the order of examinations were consistent between different groups. We analyzed the anxiety level before cystoscopy, the maximum pain during the examination and the change of lower urinary tract symptoms (LUTS) before and after cystoscopy. Meanwhile, we analyzed the rate of gross hematuria and pyuria after cystoscopy. The anxiety and pain levels were evaluated by the Amsterdam Preoperative Anxiety and Information Scale (APAIS) and visual analogue scale (VAS). LUTS was reflected by the Core Lower Urinary Tract Symptom Score (CLSS). We distinguished gender during analysis.
RESULTS
The median APAIS score of male patients undergoing flexible or rigid cystoscopy was 8 vs. 12 (p < 0.01), and this result for females was 8 vs. 9 (p = 0.048). The median pain scores for men in the two groups was 1 vs. 2 (p < 0.01), respectively, and this outcome in female patients was 0 vs. 1 (p < 0.01). Patients in the rigid group had more CLSS change (0 vs. 1, p < 0.01). There was no difference in pyuria or gross hematuria rate after examination. Analysis in respective groups showed that men have more severe pain than women, 1 vs. 0 (p = 0.001) in the flexible group and 2 vs. 1 (p = 0.009) in the rigid group.
CONCLUSIONS
A flexible cystoscope can improve anxiety and subjective feelings of BC patients during cystoscopy follow-up.

Acute focal bacterial nephritis (AFBN) is a localized bacterial infection of the kidneys presenting as an inflammatory mass that can develop into renal abscess. The current reports on AFBN mostly are among children and rarely described in adults. This study was aimed to analyze the clinical features of AFBN in adults and make a review for the disease to give the clinicians some clues to suspect and recognize it in adults. From January 2014 to December 2019, AFBN was diagnosed by contrast-enhanced computed tomography (CT) in 238 adults at the Department of Nephrology, the Second Hospital of Hebei Medical University, Shijiazhuang, China. We reviewed the clinical records of these patients and asked them about their post-discharge status via telephone follow-up. Of all the patients, 195 were female and 43 were male, the median age were 46.87 years. 86.13% presented with fever, 55.89% presented with lower urinary tract symptoms and 97.9% presented with pyuria. In renal ultrasonography, abdominal findings were seen only 22.69% patients. E.coli accounted for 74.73% of the isolated pathogen. After 4 weeks of treatment, the patients had no recurrence of symptoms. We recommend that when a patient presents clinically with acute pyelonephritis, but the fever persist longer after antimicrobial treatment (≥ 4 days in our study), AFBN should be suspected. For the diagnosis, contrast-enhanced CT is the "gold standard", magnetic resonance imaging (MRI) may be a good option, but the ultrasonography is probably not satisfied. 3-4 weeks of antibiotic therapy may be appropriate for AFBN in adults.

Observational Study
BACKGROUND
Current evidence does not recommend screening urine culture and curing asymptomatic bacteriuria (ASB) before joint arthroplasty. The bacteriuria count on pre-operative urinalysis is a more common clinical parameter. We aimed to investigate whether the bacteriuria count on preoperative urinalysis can increase postoperative wound complications in primary total hip arthroplasty (THA).
METHODS
We conducted a retrospective study that included patients who underwent primary THA in our institution from 2012 to 2018. We obtained preoperative urinalysis results before THA during the same hospitalization and identified patients with abnormal urinalysis. Receiver operating characteristic (ROC) curves were first generated to evaluate the predicted value of leukocyte esterase (LE), nitrite, bacteriuria, and pyuria in the urinalysis for superficial wound infection. Then, all included patients were divided into two groups according to the preoperative urinalysis: a bacteriuria-positive group and a bacteriuria-negative group. The primary outcome was the superficial wound infection rate within 3 months postoperatively, and the secondary outcomes included wound leakage, prosthetic joint infection (PJI), pulmonary infection, urinary tract infection (UTI), readmission rate within 3 months postoperatively, and length of stay (LOS) during hospitalization. We utilized univariable analyses to compare the outcomes between the two groups. A multivariable logistic regression model was generated to explore the potential association between bacteriuria and the risk of superficial wound infection, wound leakage, and readmission rate controlling for baseline values.
RESULTS
A total of 963 patients were included in the study. One hundred sixty patients had abnormal urinalysis. The AUCs for LE, nitrite, bacteriuria, and pyuria were 0.507 (95% confidence interval (CI), 0.315 to 0.698), 0.551 (0.347 to 0.756), 0.675 (0.467 to 0.882), and 0.529 (0.331 to 0.728), respectively. Bacteriuria was diagnostically superior to LE, nitrite, and pyuria. Among the 963 patients, 95 had a positive bacteriuria on preoperative urinalysis, and only 9 (9.5%) had a positive urine culture. Compared with the bacteriuria-negative group, the bacteriuria-positive group had a higher superficial wound infection rate (4.2% vs. 0.6%, P = 0.008), higher wound leakage rate (11.6% vs. 4.5%, P = 0.007), higher readmission rate (5.3% vs. 1.3%, P = 0.015) within 3 months postoperatively and longer LOS (6.19 ± 2.89 days vs. 5.58 ± 2.14 days, P = 0.011). After adjustment, the bacteriuria-positive group had a significantly increased risk of superficial wound infection (OR = 7.587, 95%CI: 2.002 to 28.755, P = 0.003), wound leakage (OR = 3.044, 95%CI: 1.461 to 6.342, P = 0.003), and readmission (OR = 4.410, 95%CI: 1.485 to 13.097, P = 0.008).
CONCLUSION
Preoperative bacteriuria positivity on urinalysis significantly increased the risk of postoperative wound complications, readmission, and LOS in primary THA regardless of the result of the urine culture. Urinalysis is a fast and cost-acceptable test whose advantages have been underestimated.

BACKGROUND
Unilateral small-sized kidney is a radiological term referring to both the congenital and acquired causes of reduced kidney volume. However, the hypoplastic kidney may have peculiar clinical and radiological characterizations.
AIM
To evaluate the clinical presentations, complications, and management approaches of the radiologically diagnosed unilateral hypoplastic kidney.
METHODS
A retrospective review of the records of patients with a radiological diagnosis of unilateral hypoplastic kidney between July 2015 and June 2020 was done at Assiut Urology and Nephrology Hospital, Assiut University, Egypt.
RESULTS
A total of 33 cases were diagnosed to have unilateral hypoplastic kidney with a mean (range) age of 39.5 ± 11.2 (19-73) years. The main clinical presentation was loin pain (51.5%), stone passer (9.1%), anuria (12.1%), accidental discovery (15.2%), or manifestations of urinary tract infections (12.1%). Computed tomography was the most useful tool for radiological diagnosis. However, radioisotope scanning could be requested for verification of surgical interventions and nephrectomy decisions. Urolithiasis occurred in 23 (69.7%) cases and pyuria was detected in 22 (66.7%) cases where the infection was documented by culture and sensitivity test in 19 cases. While the non-complicated cases were managed by assurance only (12.1%), nephrectomy (15.2%) was performed for persistent complications. However, symptomatic (27.3%) and endoscopic (45.6%) approaches were used for the management of correctable complications.
CONCLUSION
Unilateral hypoplastic kidney in adults has various complications that range from urinary tract infections to death from septicemia. Diagnosis is mainly radiological and management is usually conservative or minimally invasive.

Granulomatosis with polyangiitis (GPA) is an uncommon pauci-immune small-vessel necrotising granulomatous vasculitis mostly seen in age 45-60 years. We present the case of a formerly healthy 44 years old male presenting with dysuria and intermittent urinary retention for 8 months, not responding to empirical antibiotic therapy and TURP. A prostate biopsy showed necrotising granulomatous prostatitis. Urinalysis demonstrated persistent pyuria and haematuria, but cultures showed no growth. Subsequently he complained of fever, cough, dyspnoea and skin ulcers. CT of the chest showed multiple cavitatory lesions and pleural effusion. On work up, c-ANCA was positive and a diagnosis of granulomatosis with polyangiitis was established. This depicts a rarely seen presentation of prostatitis as the initial feature of GPA.

OBJECTIVE
Urinary tract infections (UTI) are the second most common infection in geriatric population. This study investigated clinical findings, diagnostic approaches, complicating factors, prognosis, causative microorganisms and antimicrobial susceptibility in geriatric patients diagnosed with UTI.
METHODS
A total of 140 hospitalised patients with UTIs were evaluated within three years between January 2011-January 2015 at the Eskisehir Yunus Emre State Hospital. UTI diagnosed when there were systemic and urinary signs and symptoms and a positive dipstick test and urine culture result, leukocyte and CRP like serum parameters.
RESULTS
Among the studied patients, 41.4% had urological diseases, 20.7% had diabetes mellitus and 19.2% had neurological diseases. The most common symptoms and signs were fever, dysuria nausea/vomiting, general condition impairment, pyuria, haematuria. The laboratory values for CRP, ESR and leukocyte count were 84 mg/dL, 56 mm/s and 11.9 (10^3μL), with mean values being determined. Among patients having a urinary catheter (17.1%), 27.9% had a history of UTI, while 29.3% had been hospitalised. and were the most commonly identified microorganisms. The mean duration for hospitalisation was 7.6 days, while a 5% mortality rate was observed over the course of the disease.
CONCLUSION
Because of the potential for serious complications and mortality, elderly patients with urinary tract infection, should receive immediate empirical treatment based on anamnesis, clinical evaluation and urinalysis and should be re-examined using results from cultures and antibiograms upon follow-up.

Comparative Study
INTRODUCTION
Renal involvement is a rare complication of β-thalassemia. Both tubular and glomerular dysfunction might occur in these patients. The aim of this study was to evaluate and compare kidney function in the major, intermedia, and minor variants of β-thalassemia.
MATERIALS AND METHODS
Renal tubular and glomerular function of 72 patients with β-thalassemia (25 major, 23 intermedia, and 24 minor) were evaluated. Patients older than 40 years and those with chronic kidney disease, diabetes mellitus, congestive heart failure, associated infections, congenital anomalies of the kidney and urinary tract were excluded. Blood and urine samples were collected electrolytes and markers of kidney function.
RESULTS
Mean age at the time of study was significantly higher in the minor group. The majority of patients with thalassemia major were males. Hematuria and pyuria occurred in 4% to 8% of the patients. Serum level of all variables were within normal limits, with no significant difference between the three groups. Glomerular filtration rate was nonsignificantly higher in the major and intermedia groups, compared to the minor variant. A significantly lower urine phosphorus and uric acid excretion was noted with the minor variant. Urine phosphorus and uric acid excretion increased more frequently in the major and intermedia groups.
CONCLUSIONS
Tubular and glomerular functions appear to be well preserved in all variants of β-thalassemia.

Meta-Analysis Review
BACKGROUND
It has been recognized that the incidence of prostatic utricle in boys is increasing and is closely associated with diseases such as hypospadias. However, the clinical features of prostatic utricle with normal external genitalia have received little attention.
METHODS
Based on this, a series of 22 male children with prostatic utricles has been compiled by adding our 3 patients to 19 cases reported. All children enrolled had normal external genitalia. Clinical data of the case was reviewed.
RESULTS
Urinary tract infection, purulent urethral discharge and pyuria were the most common presenting chief complaint (41%), irritative lower urinary tract symptoms were present in 17% of cases, obstructive lower urinary tract symptoms were noted in 14%. Urinary retention has been reported in 18% and epididymitis has been reported in 14%. Relatively rare clinical symptoms are abdominal pain, hematuria, and hematospermia. A case of calculus formation and a case of neoplasia within the prostatic utricle has been reported. A cystic mass found by digital rectal examination is the most common presenting sign. A utricular lesion posterior to the bladder was revealed by imaging examination. Unilateral renal agenesis was associated in 32% of reports. Non-surgical approach was chosen in 3 cases, transrectal ultrasonography guided aspiration has been reported in 1 case. Endoscopic techniques were used in 3 cases. Open excision was used in 11 cases. The laparoscopic excision was chosen in 3 cases and Robot-assisted laparoscopy was reported in 1 case. Symptoms and signs disappeared after treatment in all children, and no recurrence occurred during follow-up.
CONCLUSIONS
Prostate utricles without external genital anomalies are rarely reported in children, and are easily missed and misdiagnosed, often accompanied by recurrent urinary tract infections, lower urinary tract symptoms, epididymitis, dysuria and other symptoms. Imaging studies can confirm the diagnosis. Symptomatic and large utricles should be actively treated. The treatment program should be based on the age, clinical symptoms, and size and location of the utricle.

Updated evidence of the safety and efficacy of the miniaturized percutaneous nephrolithotomy with holmium laser lithotripsy for the treatment of recurrent nephrolithiasis.
OBJECTIVE
The objective of the present communication is to report the safety and efficacy of applying miniaturized percutaneous nephrolithotomy (mini-PCNL) in Vietnamese patients with recurrent kidney stones using a miniature nephroscope through a 18F metal access sheath.
PATIENTS AND METHODS
We performed a retrospective cohort study of patients who were diagnosed with recurrent nephrolithiasis and underwent mini-PCNL after previous treatments between 2017 and 2020. Clinical profile, preoperative characteristics, intraoperative events, and postoperative outcomes were obtained from the hospital database. Descriptive statistics were used for the whole analysis.
RESULTS
Of 89 eligible patients, 54 were male. The mean age was 53.4 years. Mean stone size was 24.9 mm. 37 patients had right side stone, 39 had left side stone, and 13 had stone on both sides. Pain in the flanks and back was the most symptom in our patients (n = 87, 97.8%), followed by hematuria (n = 13, 14.6%), dysuria (n = 8, 8.9%), fever (n = 7, 7.9%), acute renal colic (n = 5, 5.6%), and pyuria in 2 patients. 27 had complex stones, and the remaining stone position included renal pelvis (21, 23.6%), upper calyx (15, 16.9%), lower calyx (14, 15.7%), and middle calyx (12, 13.5%). 35 of them had grade I, 27 grade II, 8 grade III and 2 grade IV of hydronephrosis. Renal failure was documented in 12 patients (13.5%). 18 patients were performed with 2-times punctures (20.2%) and 13 with 3-times punctures (14.6%). We used one percutaneous tract in 79 patients and the remaining 10 were performed with two tracts. The upper, middle, and lower calyx was the site of puncture access in 6 (6.7%), 73 (82.0%), and 10 (11.3%) cases, respectively. 3 patients had bleeding requiring intraoperative blood transfusion and 2 were converted to open surgery. Intraoperative parameters recorded percutaneous puncture duration of 20.9 minutes (5-50), and total operative duration of 112.9 minutes (40-240). 7 patients developed secondary bleeding after surgery, besides 5 cases of fever, 2 cases of septic shock and one case of drainage failure. Early stone-free rate was 89.9% and this rate was 94.4% for patients after one month of mini-PCNL. Mean duration of ureteral catheter circulation was 2.7 days (2-20), mean length of postoperative hospitalization was 6.6 days (4-25) and mean total hospital stay was 12.9 days (7-28).
CONCLUSIONS
Present results show the safety of mini-PCNL with respect to recurrent nephrolithiasis. Our updated evidence may provide appropriate modified approaches that aim at reducing the risk of recurrent kidney stone development.
