Authors present a case of 50-year-old man with penoscrotal hypospadias in whom using one-stage techniques repair urethra was reconstructed with good functional and cosmetic effect.
Congenital anomalies of structures originating from Mullerian ducts are important gynecological problem. They often coexist with malformations of urinary tract. In this report we describe the case of 31 year old women with didelphus and bladder extrophy. The surgical treatment consisted on transabdominal total hysterectomy due to endometriosis IV (rAFS) narrowing ureteroenterostomy.
OBJECTIVE: To identify the difficulties in diagnosing bladder outlet obstruction in women. MATERIAL AND METHODS: 53 women with a mean age of 37.2 (range 16-70) with chronic lower urinary tract symptoms and no neurogenic or organic diseases were examined. The prevalent symptoms were frequency (96%), urgency (92%) and nocturia (75%), and the mean duration of symptoms was 3.8 years. After pressure-flow studies and voiding cystourethrography were conducted, patients either underwent bladder neck or urethral incisions based on their diagnosis. These patients were subsequently subjected to follow-up uroflow studies. RESULTS: Abnormal uroflow curves were observed in 19 of 53 women. In 10 of them (52.6%), bladder outlet obstruction based on pressure-flow results was confirmed. Voiding cystourethrography results from these 19 women confirmed that 17 patients had bladder neck obstruction, while the remaining 2 had urethral obstruction. 16 of 19 were treated endoscopically, with 14 patients undergoing bladder neck incisions through the 5- and 7-o'clock positions and 2 patients having a distal urethral incision through the 12-o'clock position. In all of these 16 cases, there were both a statistical increase in the maximum flow rate (Qmax) as well as an improvement in the flow curves. Symptomatic improvement was observed in 12 of the 16 women subjected to surgical intervention. CONCLUSION: Bladder outlet obstruction exists in women with lower urinary tract symptoms. Pressure-flow studies and voiding cystourethrography are reliable modalities for confirming bladder outlet obstruction. Bladder outlet obstruction can be functionally or structurally caused.
Urinary tract infections are the most frequent complications after renal transplantation. A retrospective study was conducted in patients treated after renal transplantation. We paid special attention to urinary tract infection connected with urologic complications and other urologic diseases.
The effectiveness of neodymium laser therapy was presented in the treatment of urogenital condyloma acuminata in 55 patients (51 men and 4 women). The patients were followed up 14 days, 4 weeks, 3 months and 6 months after the laser treatment. The main localization of condyloma acuminata was foreskin and glans penis. The cure rate after the 1st session of treatment was 76%, 8.5% of patients required 3 sessions of the laser therapy. After 6 months 7 patients discontinued the follow-up, 89.6% (43 patients) were cured, 2 had the scars of foreskin and 3 suffered from recurrences. Neodymium laser treatment of urogenital condyloma is a safe treatment and no major side effects were encountered.
We describe a case of a 50-year-old man with lesions localized in the region of urethral meatus and on the epithelium of the foreskin. The lesions were observed as the white spots with flat or somewhat depressed surface, locally similar to leukoplakia, lichen sclerosus atrophicus or cicatrix, without any subjective symptoms. Cystoscopy, micturition urography and biopsy were performed by urologist. The diagnosis of lichen planus Wilsoni was made based on the biopsy examination. We obtained great improvement of lesions through the applied local therapy
There we presented three cases of ureteral injury after gynecological operations. In two cases partial ureteral obstruction was treated by creating percutaneous renal fistula. In the latter case, in spite of conservative treatment (double J catheter), a uretero-vaginal fistula was detected.
