[Treatment of female stress urinary incontinence with the TVT (tension-free vaginal tape) system: our experience].

INTRODUCTION: The TVT system is a new surgical procedure for female stress urinary incontinence. The object of this study is to report our initial experience with this technique. We report our results and complications too. MATERIAL AND METHODS: From April 1999 to July 2000, 23 systems TVT was implanted in our hospital. The patients were followed for a 6 to 21 month period. All the patients had stress incontinence. The mean age was 59 years. Gynaecological surgery was associated in 4 patients. One of them was excluded because a diagnosis mistake. TVT implies the implantation of a prolene tape around mid-urethra via a minimal vaginal incision. RESULTS: 17 patients (77.27%) had a significantly improved in the post-operative evaluation. The mean post-surgical stay in the hospital was 1.7 days. A bladder base was damaged during the surgery. No urinary retention, erosion or urethral lesion were found. CONCLUSIONS: We consider the TVT operation to be a safe and effective surgical procedure for the treatment of female urinary stress incontinence. This surgery is easy to lean, fast, cheap and with a low rate of complications.

[Partial nephrectomy in lithiasis].

OBJECTIVE: To analyze our series of patients with renal lithiasis who underwent partial nephrectomy from 1980-1999. METHODS: 28 patients who underwent partial nephrectomy were analyzed (22 females; mean age 48.09 years, and 6 males; mean age 60 years). Surgery for lithiasis had been previously performed in 5 renal units. Nine patients had previously undergone ESWL (more than 3 sessions), all of whom subsequently developed multiple residual calculi. Twelve patients had a microbiologically confirmed positive urine culture. The renal lithiasis amenable to treatment by partial nephrectomy was frequently localized in the lower calyces (17 cases). RESULTS: Histopathological analysis of the nephrectomy specimen showed a prevalence of signs of chronic parenchymal atrophy (25 cases). Three cases showed segmental renal dysplasia (those in whom a superior heminephrectomy was performed for duplex excretory system). Fifty percent of the stone fragments analyzed showed calcium phosphocarbonate. Eight patients had postoperative complications; the most important were two cases of renal cutaneous fistula and one subphrenic abscess. At 9 1/2 years' mean follow-up, renal function is normal in 25 patients. Lithiasis developed in the contralateral unit in 6 cases and in the same renal unit in one case. CONCLUSIONS: Partial nephrectomy continues to be a therapeutic option for lithiasis. Its indication depends on the morphological and functional characteristics of the compromised renal unit, especially in those cases in whom renal preservation can be obviated due to its scanty significance.

[Comparative study of ureteral anastomosis with or without double-J catheterization in renal transplantation].

OBJECTIVE: To analyze the impact of the use of the routine double-J stent in the incidence of urological complications, like fistula, stenosis, ureteral obstruction and urinary tract infection. METHODS: A retrospective study was conducted on two groups of patients: 28 without double-J stent and 28 with it. We reviewed urological complications: stenosis, fistula and obstruction. We paid special attention to urinary tract infection and other inherents complications to the use of double-J stents. RESULTS: A patient from the double-J stended group (3.6%) developed a urinary fistula and there were no obstructions. 13 patients (46.6%) had a positive urinary culture in the first month post RT. Two urinary fistulas and 4 obstructions were developed in the non-stended group. Six major complications of the urinary tract. 14 patients (50%) had a positive urinary culture in the first month post RT. CONCLUSIONS: The use of double-J stent across uterovesical anastomosis decreases the post-RT ureteral complications. Stent placement does not increase the risk of urinary tract infection in the early post-RT.
