PURPOSE: The definition of posttransobturator tape procedure (post-TOT) voiding dysfunction (VD) is inconsistent in the literature. In this study, we retrospectively investigated the risk factors for post-TOT VD by applying various definitions in one cohort. MATERIALS AND METHODS: The medical records of 449 patients were evaluated postoperatively. Acute urinary retention requiring catheterization, subjective feeling of voiding difficulty during follow-up, and postoperative postvoid residual (PVR) greater than 100 mL or PVR greater than 50% of voided volume (significant PVR) were adopted for the definition of VD. With these categories, multivariate analysis was performed for risk factors of postoperative VD. RESULTS: Ten patients (2.2%) required catheterization, 47 (10.5%) experienced postoperative voiding difficulty, and 63 (14.7%) showed significant PVR. In the multivariate logistic analysis, independent risk factors for postoperative retention requiring catheterization were previous retention history (p=0.06) and preoperative history of hysterectomy. Risk factors for subjective postoperative voiding difficulty were underactive detrusor (p=0.04) and preoperative obstructive voiding symptoms (p<0.01). Previous urinary retention history (p<0.01)) was an independent risk factor for concomitant postoperative voiding difficulty and significant PVR. Spinal anesthesia (p=0.02) and previous urinary retention history (p=0.02) were independent risk factors for significant postoperative PVR. CONCLUSIONS: With the use of several definitions of VD after the midurethral sling procedure, postoperative peak flow rate and PVR were significantly different between groups. Although there were no independent risk factors consistent with various definitions of VD, preoperative obstructive voiding symptoms and objective parameters suggesting impaired detrusor tend to have predictive power for post-TOT VD.

PURPOSE: We aimed to analyze the characteristics of urinary retention (UR) in female inpatients managed with medical treatments. MATERIALS AND METHODS: We retrospectively analyzed the medical records of female inpatients referred to the department of urology for UR at our institution from January 2009, to December 2014. UR was defined as a difficulty in self-voiding despite a sufficient urine volume or >300-mL postvoid residual. The data included patients' age, body mass index (BMI), ambulatory status, medical and surgical history, classes of taking drugs, and urinary tract infection. RESULTS: A total of 182 women were included as retention group, mean age of 72.64±12.94 years and BMI of 22.94±3.10 kg/m2. In the chi-square analysis, cardiovascular disorders (p=0.000), diabetes mellitus (p=0.008), metastatic malignancy (p=0.008), chronic renal disorders (p=0.028) were found significantly. In the multiple logistic regression analysis, cardiovascular disorders (p=0.002; odds ratio [OR], 0.491), metastatic malignancy (p=0.013; OR, 2.616) were found to increase the risk of UR. The most common surgical history was anti-incontinence surgery (7.2%). In term of medication use, the most prescribed agents were nonsteroidal anti-inflammatory drugs (NSAIDs) (53.8%). The patients taking multiple drugs with antimuscarinic effects except of NSAIDs, narcotics and diuretics were 48 (26.4%). Urinary tract infection was identified in 43 patients (23.6%). CONCLUSIONS: UR in females managed with medical treatments could be occurred occasionally. We think that thorough attentions are needed for UR to patients with cardiovascular disorders including diabetes mellitus, metastatic malignancy, chronic renal disorders urinary tract infection, and more careful interests when managing with drugs with antimuscarinic effects.

PURPOSE: To evaluate the medium-term efficacy and safety of transobturator four-arm polypropylene mesh in the treatment of high-stage anterior vaginal wall prolapse and concomitant stress urinary incontinence (SUI). MATERIALS AND METHODS: Between September 2010 and August 2013, a prospective single-center trial was performed to evaluate women with stage> or =3 anterior vaginal wall prolapse with or without SUI who presented to Labbafinejad Hospital, Teheran, Iran, and underwent anterior vaginal wall repair with polypropylene mesh. Pre- and postoperative evaluation included history; physical examination using the Pelvic Organ Prolapse Quantification system and cough stress test, both before and after reduction of prolapsed structures; Pelvic Floor Distress Inventory (PFDI) and Pelvic Floor Impact Questionnaire (PFIQ); urinalysis and culture; and a postvoid residual assessment. Complications were reported at a mean of 2 years of follow-up. RESULTS: A total of 71 patients underwent cystocele repair with the transobturator four-arm polypropylene mesh. Seven of the patients were lost to follow-up. There were no perioperative complications. The anatomical success rate was 87.5%. The subjective success rate was 92.1%. The PFDI and PFIQ were significantly improved after surgery (p<0.001). Among those with the simultaneous complaint of SUI, 82% were cured without any additional procedure. Three patients (4.6%) experienced vaginal mesh extrusion. Two patients (3.1%) reported worsening of dyspareunia after surgery. CONCLUSIONS: The four arms polypropylene mesh is an effective device for simultaneous correction of anterior vaginal wall prolapse and SUI with a low complication rate at a medium-term follow-up. The majority of the subgroup with concomitant SUI were cured without a second simultaneous procedure.

PURPOSE: We compared bladder and urethral functions following radical prostatectomy (RP) between men with and without urinary incontinence (UI), using a large-scale database from SNU-experts-of-urodynamics-leading (SEOUL) Study Group. MATERIALS AND METHODS: Since July 2004, we have prospectively collected data on urodynamics from 303 patients with lower urinary tract symptoms (LUTS) following RP at three affiliated hospitals of SEOUL Study Group. After excluding 35 patients with neurogenic abnormality, pelvic irradiation after surgery, or a history of surgery on the lower urinary tract, 268 men were evaluated. We compared the urodynamic findings between men who had LUTS with UI (postprostatectomy incontinence [PPI] group) and those who had LUTS without UI (non-PPI group). RESULTS: The mean age at an urodynamic study was 68.2 years. Overall, a reduced bladder compliance (< or =20 mL/cmH2O) was shown in 27.2% of patients; and 31.3% patients had idiopathic detrusor overactivity. The patients in the PPI group were older (p=0.001) at an urodynamic study and had a lower maximum urethral closure pressure (MUCP) (p<0.001), as compared with those in the non-PPI group. Bladder capacity and detrusor pressure during voiding were also significantly lower in the PPI group. In the logistic regression, only MUCP and maximum cystometric capacity were identified as the related factor with the presence of PPI. CONCLUSIONS: In our study, significant number of patients with LUTS following RP showed a reduced bladder compliance and detrusor overactivity. PPI is associated with both impairment of the urethral closuring mechanism and bladder storage dysfunction.

PURPOSE: To investigate the differences in the cancer detection rate and pathological findings on a second prostate biopsy according to benign diagnosis, high-grade prostatic intraepithelial neoplasia (HGPIN), and atypical small acinar proliferation (ASAP) on first biopsy. MATERIALS AND METHODS: We retrospectively reviewed the records of 1,323 patients who underwent a second prostate biopsy between March 1995 and November 2012. We divided the patients into three groups according to the pathologic findings on the first biopsy (benign diagnosis, HGPIN, and ASAP). We compared the cancer detection rate and Gleason scores on second biopsy and the unfavorable disease rate after radical prostatectomy among the three groups. RESULTS: A total of 214 patients (16.2%) were diagnosed with prostate cancer on a second biopsy. The rate of cancer detection was 14.6% in the benign diagnosis group, 22.1% in the HGPIN group, and 32.1% in the ASAP group, respectively (p<0.001). When patients were divided into subgroups according to the number of positive cores, the rate of cancer detection was 16.7%, 30.5%, 31.0%, and 36.4% in patients with a single core of HGPIN, more than one core of HGPIN, a single core of ASAP, and more than one core of ASAP, respectively. There were no significant differences in Gleason scores on second biopsy (p=0.324) or in the unfavorable disease rate after radical prostatectomy among the three groups (benign diagnosis vs. HGPIN, p=0.857, and benign diagnosis vs. ASAP, p=0.957, respectively). CONCLUSIONS: Patients with multiple cores of HGPIN or any core number of ASAP on a first biopsy had a significantly higher cancer detection rate on a second biopsy. Repeat biopsy should be considered and not be delayed in those patients.

6.Influence of vascular endothelial growth factor inhibition on simple renal cysts in patients receiving bevacizumab-based chemotherapy.
Korean Journal of Urology 2015;56(12):791-795
PURPOSE: Although angiogenesis has been implicated in the promotion of renal cyst growth in autosomal dominant polycystic kidney disease, no studies have investigated the role of angiogenesis in the growth of simple renal cysts. The aim of current study was to investigate the effect of chemotherapy with the antivascular endothelial growth factor antibody bevacizumab on renal cyst development and growth in cancer patients. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 136 patients with a variety of cancers that were treated with bevacizumab-based chemotherapy for metastatic disease. The presence of and changes in renal cysts were evaluated by retrospective analysis of computed tomography scans performed for assessment of tumor response to bevacizumab-based therapy. RESULTS: The median age of the patients was 64 years. Renal cysts were identified in 66 patients, in whom 33 (50%) had a single cyst and the rest had 2 or more cysts. The average dose of bevacizumab was 2.68 mg/kg per week. Median duration of treatment was 33 weeks. Average cyst size was 1.9±2.4 cm at the beginning of the study and the majority of the cysts (54 patients, 84%) did not change in size or shape during bevacizumab treatment. No patients were identified with new cysts. Cyst size changed in 10 patients (16%): an increase of 15% to 40% from the baseline size in 5 patients and a decrease in size of 10% to 70% in another 5 patients. The duration of bevacizumab therapy was significantly longer in the subgroup of patients with diminished or increased cyst size than in the patients with stable cyst size: 62 weeks versus 29 weeks, respectively (p=0.0002). CONCLUSIONS: Our data demonstrated that simple renal cysts were stable in size and number in the vast majority of cancer patients treated with bevacizumab.

Laparoscopic retroperitoneal lymph node dissection, especially when performed with the da Vinci Surgical System (Intuitive Surgical), has shown excellent cosmetic results with similar oncologic outcomes to those of open surgery. In this study, we present a case of robot-assisted retroperitoneal lymph node dissection performed in an 18-year-old man who was diagnosed with a stage IIIb mixed germ cell tumor and who was initially treated with radical orchiectomy, followed by chemotherapy. This case shows that robot-assisted retroperitoneal lymph node dissection is technically feasible, safe, and cosmetically favorable, even when performed on patients with high-stage disease or after chemotherapy.

PURPOSE: We undertook this study to evaluate the incidence, risk factors, management, and outcome of postoperative ureteral obstruction after endoscopic treatment for vesicoureteral reflux (VUR). MATERIALS AND METHODS: Ninety patients undergoing endoscopic treatment for VUR were retrospectively reviewed and classified into two groups according to ureteral obstruction: the nonobstruction group (83 cases, 122 ureters; mean age, 7.0+/-2.8 years) and the obstruction group (7 cases, 10 ureters; mean age, 6.2+/-8.1 years). We analyzed the following factors: age, sex, injection material, laterality, voiding dysfunction, constipation, renal scarring, preoperative and postoperative ultrasound findings, endoscopic findings, injection number, and injection volume. Additionally, we reviewed the clinical manifestations, natural course, management, and outcome of ureteral obstruction after endoscopic treatment. RESULTS: The incidence of ureteral obstruction after endoscopic treatment was 7.6% (10/132 ureters). The type of bulking agent used and injection volume tended to be associated with ureteral obstruction. However, no significant risk factors for obstruction were identified between the two groups. Three patients showed no symptoms or signs after the onset of ureteral obstruction. Most of the patients with ureteral obstruction experienced spontaneous resolution within 1 month with conservative therapy. Two patients required temporary ureteral stents to release the ureteral obstruction. CONCLUSIONS: In our experience, the incidence of ureteral obstruction was slightly higher than in previous reports. Our study identified no predictive risk factors for developing ureteral obstruction after endoscopic treatment. Although most of the ureteral obstructions resolved spontaneously within 1 month, some cases required drainage to relieve symptoms or to prevent renal function deterioration.

PURPOSE: To investigate surgical outcomes between retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PNL) groups for a main stone sized 15 to 30 mm and located in the lower-pole calyx. MATERIALS AND METHODS: Patients who underwent PNL or RIRS for a main stone sized 15 to 30 mm and located in the lower-pole calyx were retrospectively reviewed. Each patient in the RIRS group was matched to one in the PNL group on the basis of calculated propensity scores by use of age, sex, body mass index, previous treatment history, stone site, maximum stone size, and stone volume. We compared perioperative outcomes between the unmatched and matched groups. RESULTS: Patients underwent PNL (n=87, 66.4%) or RIRS (n=44, 33.6%). After matching, 44 patients in each group were included. Mean patient age was 54.4+/-13.7 years. Perioperative hemoglobin drop was significantly higher and the hospital stay was longer in the PNL group than in the RIRS group. The operative time was significantly longer in the RIRS group than in the PNL group. Stone-free rates were higher and complications rates were lower in the RIRS group than in the PNL group without statistical significance. The presence of a stone located in the lower-anterior minor calyx was a predictor of stone-free status. CONCLUSIONS: RIRS and single-session PNL for patients with a main stone of 15 to 30 mm located in the lower-pole calyx showed comparable surgical results. However, RIRS can be performed more safely than PNL with less bleeding. Stones in the lower-anterior minor calyx should be carefully removed during these procedures.
