Posterior urethral valves represent the most common cause of bladder outlet obstruction in children. The valves can be diagnosed by clinical symptoms and findings of VCUG, and must be confirmed and treated by endoscopic methods. Htrein typical endoscopic appearance of posterior urethral valve is presented with brief review of literature.

Thirteen patients with contracted bladder due to tuberculosis who underwent surgical intervention were evaluated The most common agonizing symptom was frequency. Surgical management included augmentation cystoplasty in 8 patients and urinary diversion in 5 patients. In augmentation cystoplasty, the overall success rate of 87.5 % has been achieved in view of relief of symptom, improvement of bladder capacity and preservation of renal function. For the success of augmentation cystoplasty, creatinine clearance higher than 30 ml/min., no abnormality in selected intestinal segment, absence of uninhibited detrusor contraction or detrusor-sphincter-dyssynergia and no bladder outlet obstruction are inevitable. As an alternative, urinary diversion should be considered only in cases of severely deteriorated renal function, severely decreased bladder capacity, bladder outlet obstruction, neurogenic bladder and inapplicability of augmentation cystoplasty.

Urinary incontinence is one of the most distressing problems in urologic practice. However, recent advances in implantable devices have significantly improved the outlook for patients with incontinence due to sphincter weakness. Herein we report a case of urinary incontinence treated by artificial sphincter (model AMS 800) implantation. A 25-year-old man presented with continuous and total incontinence, which developed after pelvic bone fracture and urethral injury. cystometry was normal, uroflowmetry and urethrography showed no significant bladder outlet obstruction, and urethral closing pressure was significantly decreased. After artificial sphincter implantation to the bladder neck. the patient showed good results both clinically and urodynamically.

Most prostatic cysts are not symptomatic and are found incidentally. There have been some reports of prostatic cysts presenting as an infravesical obstruction. Our case is the second published report of an anteriorly positioned midline prostatic cyst of the bladder neck. The prostatic cyst in a 41-year-old man presenting with lower urinary tract symptoms was located in the anterior and midline area of the prostate and was protruding into the bladder neck at the precise twelve o'clock position. The cyst obstructed the bladder neck by acting like a checking valve. Transurethral resection of the cyst was performed, and the obstructive symptoms successfully improved.

PURPOSE: We evaluated the clinical significance of simultaneous transurethral resection of bladder tumor(TURB) and the prostate(TURP) in patients who have superficial bladder cancer with bladder outlet obstruction. MATERIALS AND METHODS: Between April 1997 to April 2006, 213 patients with superficial bladder cancer were included in this study. The patients were treated with TURB only(n=107, Group I) or TURB with TURP (n=106, Group II). Bladder cancer recurrence was observed by performing cystoscopy and urine cytology. Uroflowmetry was performed three months after surgery. RESULTS: There were no significant differences in age, the tumor size or the number of tumors between groups I and II. There was no evidence of cancer implantation where TURP was applied. The recurrence rate of group II was significantly lower than that of group I(p=0.044), and the time to recurrence was longer for group II than for group I(p=0.026). There was no significant difference in the progression rate between the two groups(p=0.788). Three months after surgery, the mean residual urine volume was lower for group II(7.9ml) than that for group I(21.7ml). CONCLUSIONS: For superficial bladder cancer patients with bladder outlet obstruction, simultaneous TURB and TURP may help reduce the bladder cancer recurrence rate and delay the time to recurrence without the risk of cancer implantation at the site where TURP is applied.
