Neurofibromatosis is a rare systemic disease, and genitourinary tract involvement is especially uncommon. Bladder is the most frequently involved organ in the genitourinary tract. Bladder neurofibromatosis may present as a diffuse infiltrative process or an isolated neurofibroma. The symptoms vary, ranging from urinary incontinence to retention. Treatment is usually conservative. The patient should be worked up to rule out other manifestation of tumor enlargement and followed to evaluate the development of new lesion. We report a case of the development of invasion of bladder in a patient with neurofibromatosis.

Imperforate hymen is, with an incidence of 0.1%, a rare female anomaly, which can appear with symptoms such as lower abdominal pain, primary amenorrhea, dysuria, anuria, caused by retention of menstrual blood after the onset of menstruation. Generally urinary retention is caused by psychological conditions, drug effect, infection or congenital anomaly causing acute urinary obstruction. We experienced a patient with symptoms of acute urinary retention, suggesting acute urinary obstruction. The cause for the retention turned out to be an imperforated hymen, which should therefore be mentioned in the literature as a possible cause in cases suspected of urinary retention.

Since their introduction in 1996, tension-free midurethral slings (MUS) have been proven to have long-term efficacy and safety. They are considered the gold standard treatment of female stress urinary incontinence, especially in cases that are associated with urethral hypermobility. However, they are not free of complications and, although rare, some of these complications can be challenging for both patients and physicians. Some complications occur intraoperatively, whereas others appear in the early or late postoperative period. There is less controversy in the diagnosis and treatment of complications such as vaginal extrusion or urinary system erosion, whereas de novo voiding problems are at best not completely understood. Voiding dysfunction after MUS placement may vary in a wide range from urinary frequency or urgency to retention and is usually attributed to the obstructive or irritative effect of the sling. However, present urodynamic criteria for the diagnosis of female infravesical obstruction are not satisfactory, and the best management policy for de novo voiding dysfunction remains controversial. In the majority of cases, the diagnosis of obstruction leading to a urethral release surgery depends on a combination of several clinical findings. The timing of urethral release surgery varies depending on the preferences of the surgeon, and the outcome of this surgery is not always predictable. The purpose of this review was to assess the diagnosis and management of the immediate, short-term, and long-term complications of MUS in light of the current literature in an attempt to determine the best management policy.

PURPOSE: We compared outcomes of the U- and H-type approaches of the tension-free vaginal tape (TVT)-Secur procedure for the treatment of female stress urinary incontinence (SUI). MATERIALS AND METHODS: From March 2007 to July 2008, 115 women with SUI underwent TVT-Secur by a single surgeon. Patients were randomly assigned to either the U- or the H-type approach. After 12 months, postoperative changes in the Sandvik questionnaire, incontinence quality of life questionnaire (I-QoL), Bristol female lower urinary tract symptoms-scored form (BFLUTS-SF), and postoperative patient satisfaction were evaluated. Cure was regarded as no leakage on the Sandvik questionnaire. Complications were also evaluated. RESULTS: Of 115 women, 53 were treated with the U approach, and 62 women were treated with the H approach. At 12 months, 88.7% of those treated with the U approach and 87.1% of those treated with the H approach were cured (p=0.796). The I-QoL and filling, incontinence, sexual function, and QoL sum (BFLUTS-SF) scores were improved with both approaches, and there were no significant differences in the degree of improvement between approaches. Approximately 83.7% and 82.9% of the women treated with the U and H approaches, respectively, were satisfied with the outcome (p=0.858). There were 3 cases of intra-operative vaginal wall perforation in the H-type group. Immediate postoperative retention was observed in 2 women in the U-type group and 1 woman in the H-type group. One woman in the U-type group underwent tape releasing and cutting procedures for persistent large post-void residuals. CONCLUSIONS: The U- and the H-type approaches of the TVT-Secur procedure provided comparable effectiveness for the treatment of female SUI.

PURPOSE: Urologists occasionally experience some cases of voiding failure after transurethral resection of prostate (TURP). Preoperative and postoperative factors attributable to acute urine retention (AUR) after catheter removal in post-TURP patients were evaluated and analyzed to determine the causative factors for AUR. MATERIALS AND METHODS: From June 2004 to May 2008, a total of 172 patients who underwent TURP due to symptomatic benign prostatic hyperplasia (BPH) were divided into the AUR group (n=21) and the control group (n=151). The AUR group was defined as patients with voiding difficulty within 24 hours and whose residual urine volume was above 400 ml after catheter removal. The control group was defined as patients without AUR. Age, duration of symptoms, International prostate symptom score (IPSS), Quality of life score (QoL), uroflowmetry, post-void residual urine volume, preoperative serum prostate specific antigen (PSA) level, preoperative prostate volume, resected prostate volume, rate of prostate resection [resected prostate volume/preoperative prostate volume x 100], operative time and duration of catheter were retrospectively analyzed to identify which of these were the factors related with AUR after catheter removal in post-TURP patients. RESULTS: Preoperative prostate volume was higher (90.7+/-50.4 vs 64.4+/-32.7, p=0.002) and rate of prostate resection was lower (38.8+/-8.1 vs 50.5+/-12.4, p<0.001) in AUR group compared to control group. And age, duration of symptoms, IPSS, QoL, uroflowmetry, post-void residual urine volume, preoperative serum PSA level, resected prostate volume, operative time and duration of catheter were not statistically significant in both groups. The multivariate analysis subsequently showed that preoperative prostate volume (p=0.010, OR=1.040) and rate of prostate resection (p=0.001, OR=0.901) were independent factors related with AUR after catheter removal in post-TURP patients. CONCLUSIONS: The incidence of AUR after catheter removal was higher in post-TURP patients with high preoperative prostate volume and low rate of prostate resection. Therefore the surgeon's effort to increase the rate of prostate resection, especially in patients with large prostate volume, may lower the incidence of postoperative AUR.

PURPOSE: The aim of this study was to evaluate the efficacy and safety of hexaminolevulinate fluorescence cystoscopy in the diagnosis of bladder cancer. MATERIALS AND METHODS: In a prospective design, we included patients who had a bladder lesion suggesting bladder cancer. Patients with massive hematuria, urethral Foley catheter insertion, chronic retention state, or urinary tract infection were excluded. After the bladder was emptied, hexaminolevulinate was gently administered into the bladder. One hour later, cystoscopy under white light and blue light was performed. After marking the lesions confirmed with white light or blue light, transurethral resection of the bladder lesion and pathologic confirmation were done. Transurethral resection of the lesions that were negative in both white and blue light was also performed. RESULTS: From April 2010 to September 2010, 30 patients were enrolled. From the total of 30 patients (25 men and 5 women; mean age, 60.4+/-9.22 years), 134 specimens were extracted. Among these, 101 specimens showed positive results by blue light cystoscopy (BLC). The sensitivity of BLC and white light cystoscopy (WLC) was 92.3% and 80.8%, respectively (p=0.021). The specificity of BLC and WLC was 48% and 49.1%, respectively (p>0.05). The positive and negative predictive values of BLC were 71.2% and 81.8%, respectively, whereas those of WLC were 72.0% and 68.6%, respectively. With WLC, 48 specimens showed negative findings, but of that group, 15 specimens (31.2%) were revealed to be malignant with BLC. There were no significant side effects in the 24 hours after the instillation of hexaminolevulinate. CONCLUSIONS: Photodynamic diagnosis with hexaminolevulinate helps to find tumors that could be missed by use of WLC only. Photodynamic diagnosis might be valuable in complete resection as well as for more accurate diagnosis of bladder tumor.

PURPOSE: We performed this study to investigate the predictive factors that are related to recovery from acute urinary retention after non-urogenital surgery. MATERIALS AND METHODS: We retrospectively analyzed the records of 160 patients who were referred to the department of urology because of lasting acute urinary retention after non-urogenital surgery at our institution between January 2004 and December 2006. Patients were divided into two groups: a transient retention group, which included patients who recovered voiding capability after urinary catheterization for 7 days, and the unresponsive retention group, which included patients who did not recover voiding capability. Surgical factors, patient factors, use of patient-controlled analgesia (PCA), amount of residual urine, and medications during catheterization were analyzed. RESULTS: In the chi-square analysis, gender (female, p=0.006), age (> or=60 years old, p<0.001), preoperative voiding difficulty (p=0.028), comorbidity with hypertension (p=0.001), diabetes mellitus (p=0.003), location of surgery (pelvic cavity, p=0.005), amount of intraoperative fluid (> or =4,000 ml, p=0.002), and intraoperative indwelling of Foley catheter (p=0.026) were found to differ significantly between the two groups. In the multivariate logistic regression analysis, gender (female, p=0.002; OR=5.6), age (> or=60 years old, p=0.001; OR=5.9), hypertension (p=0.049; OR=2.6), location of surgery (pelvic cavity, p<0.001; OR=20.125), and amount of intraoperative fluid (> or =4,000 ml, p=0.001; OR=8.5) were found to increase the risk of unresponsive urinary retention. The residual urine volume of the unresponsive urinary retention group was larger than that of the transient urinary retention group (741+/-306 ml vs. 614+/-222 ml, p=0.003). CONCLUSIONS: Use of a preoperative indwelling catheter and careful management of urination is necessary to prevent unresponsive urinary retention in patients with risk factors such as female gender, old age, hypertension, surgery in the pelvic cavity, and a large amount of intraoperative fluid injection.

PURPOSE: To find the association of trial without catheter (TWOC) outcome for first spontaneous acute urinary retention (AUR) in benign prostatic obstruction with age, prior lower urinary tract symptoms (LUTS), retention volume at catheterization (RV), and size of prostate. METHODS: Our prospective observational analytical (interventional) study enrolled 77 cases of spontaneous AUR over 24 months. After clinical evaluation, digital rectal examination, and transabdominal ultrasonography, all patients were catheterized per urethra and their RV was recorded. TWOC was administered after 2 or 3 doses of 0.4 mg tamsulosin-oral absorption control system and after 48-72 hours had passed. A successful endpoint was defined as a maximum flow-rate, >5 mL/sec; voided volume, >100 mL; postvoid residue, <200 mL; and voiding within 6 hours of catheter removal. Data obtained from 58 patients were analyzed after excluding the cases lost to follow-up and secondary exclusion. Age, RV, duration of LUTS, and prostate volume on examination and ultrasonography (PUSG) were recorded and statistically analyzed. Prostate-specific antigen levels were obtained on follow-up and cases of cancer, as seen on transrectal ultrasound-guided biopsy, were secondarily excluded. RESULTS: The patients had a mean age of 65.89+/-8.67 years. Prior LUTS was seen in 35 patients (2.07+/-2.91 months). The mean PUSG and RV were 46.81+/-20.58 mL and 854.8+/-36.26 mL, respectively. Thirty patients underwent a successful TWOC; a mean age of 63.13+/-8.58 years (mean+/-standard deviation; unpaired t-test; P=0.0053) and a PUSG of < or =45 mL (Pearson chi-square test; P=0.0427) were significantly associated with a successful outcome. CONCLUSIONS: There is a significant association between TWOC outcome, age (P=0.0053), and PUSG (P=0.0427).

PURPOSE: Urinary catheterization is a common technique in clinical practice. There is, however, no consensus on management prior to removal of the indwelling catheter for short-term patients. This systematic review examined the necessity of clamping before removal of an indwelling urinary catheter in short-term patients. METHODS: A systematic literature review was conducted using eight databases and predetermined keywords-guided searches. Some 2,515 studies were evaluated. Ten studies that met the inclusion criteria were selected. RESULTS: The quality of the studies was assessed using the Jadad scoring system. Only 40.0% of studies were rated as high quality. This review found that catheter clamping prior to removal was not necessary for the short-term patient. When made a comparison with the unclamping group, there was no significant difference in recatheterization risk, risk of urine retention, patients' subjective perceptions and rate of urinary tract infection. CONCLUSIONS: This review indicated that bladder training by clamping prior to removal of urinary catheters is not necessary in short-term catheter patients. In addition, clamping carries the risk of complications such as prolonging urinary catheter retention and urinary tract injury. Further investigation requires higher quality methodologies and more diverse study designs.

OBJECTIVES: To describe the surgical technique according to personal experience, the effectiveness and safety of HoLEP. MATERIALS & METHODS: From May 2010 to April 2011, 120 consecutive patients treated with HoLEP were enrolled in this study. All patients was evaluated by digital rectal examination (DRE), transrectal ultrasonography (TRUS), serum PSA preoperatively. International Prostate Symptom Score (IPSS), peak urinary flow rate (Qmax), and postvoid residual urine (PVR) were documented preoperatively and 3 months postoperatively. The perioperative data and complications were analyzed. All procedures of HoLEP was done by single surgeon. RESULTS: The mean patient age was 68.0 (50-82), and the average operation time was 71.6 minutes (range, 30-150). Mean prostate volume was 54.1 ml (range, 20-120) and mean resected tissue weight was 7.9 g (range, 2-30). Postoperatively, IPSS and PVR decreased and Qmax increased significantly. Postoperative complications were transient incontinence, urinary retention, hematuria, urinary tract infection, urethral stricture and bladder neck contracture, and intraoperative complication was minor capsular perforation. HoLEP is a method that may completely remove prostatic adenoma tissues. In particular, its clinical effectiveness is excellent regardless of prostatic size, and it is effective even in cases with prostate volume of 100 ml or more. However, about 50 cases are needed to reach the experienced level. CONCLUSIONS: HoLEP was found to be effective and safe regardless of prostatic size. The author believe HoLEP is a size independent gold standard for BPH surgery.
