Transvaginal vs transobturator approach for synthetic sling placement in patients with stress urinary incontinence.

We present comparative short-term experience with the transvaginal (TVT) and the transobturator (TVT-O) approaches for the treatment of stress urinary incontinence (SUI). We studied 315 women with SUI, treated with a tension-free tape placement. The TVT approach was applied in 265 women, while 50 women were treated by the TVT-O approach. The mean operation time was 25 and 17 min in the TVT and TVT-O group, respectively (p<0.001). In the TVT group, continence rates were 87% after 1 year, while in the TVT-O group, the continence rate was 94%. Postoperative pain was reported in 14.4 and 28% of the TVT and TVT-O patients, respectively (p=0.02). Complications such as bladder perforation, retropubic hematoma, and urinary retention took place only in the TVT group. Urinary tract infections were recorded in 20 and 8% of the TVT and TVT-O patients, respectively (p=0.04), while vaginal erosion took place in 1.5 and 2% and de novo urgency in 14 and 8%. Both approaches show high rates of cure at the first postoperative year, while complications are less with the TVT-O procedure.

Continent urinary diversion using Mainz II modified ureterosigmoidostomy.

OBJECTIVE: To assess the surgical technique of Mainz II urinary diversion and to discuss its simplicity, quickness of performance, short postoperative period, few postoperative complications, as well as its effectiveness allowing patients to have a very good quality of life. PATIENTS AND METHODS: Over the last six and a half years, 47 patients aged between 65 and 76 years (mean age 69.9 +/- 2.5 years) underwent radical cystectomy and Mainz II ureterosigmoidostomy for invasive bladder cancer. All patients were followed according to a standard protocol including assessment of continence, renal function and acid-base balance. RESULTS: Most of the patients retained normal renal function, complete continence and acid-base balance. There were no perioperative complications. In three patients there was urine leakage. Four patients presented with pyelonephritis and needed hospitalization. Mild hyperchloraemic acidosis was seen in nine patients. Most of them were pleased from their new quality of life. CONCLUSION: The modified Mainz II ureterosigmoidostomy is a simple, quick, easy and safe procedure to achieve urinary diversion in invasive bladder cancer resulting in a very good quality of life for patients without altering their appearance and making them capable of performing all kinds of work.

Percutaneous drainage of simple cysts of the kidney: a new method.

OBJECTIVE: The experience of our department on the treatment of solitary simple kidney cysts with continuous percutaneous drainage for 24 h and instillation of pure alcohol as a sclerotic agent is reported. The results are compared with those of previous years when the treatment consisted of percutaneous drainage and injection of pure alcohol. PATIENTS AND METHODS: During the period 1992-2001, 252 patients (136 male, 116 female; aged 22-74 years) were treated at our department, and all had a solitary kidney cyst. They were treated by percutaneous drainage and then injection of pure alcohol for 20 min via a nephrostomy tube (which remained in position for 24 h). The mean follow-up period was 5 years. This cohort of patients was compared to another one of 238 patients who were treated with a previous method (126 male, 124 female; aged 28-79 years, mean 59 years). RESULTS: In 71% of the patients the symptoms and the cyst both disappeared, in 22% there was no significant recurrence (i.e. cyst diameter <5 cm), and the remaining 7% presented significant recurrence (i.e. cyst diameter >5 cm). Most of the latter cases were treated again using the same method. Of the 73 patients with impaired kidney function, in 61 (83%) this appeared to have improved as a result of our treatment. Of the 61 patients with hypertension, in 29 (47%) this appeared to have improved. There was only 1 case with complications, which presented purulence of the cyst that required open surgery. In previous case series, which were treated with percutaneous drainage and injection of pure alcohol just after the puncture of the cyst--without continuous drainage of the cyst for 24 h--only 10% of the patients had no recurrence, 30% had no significant recurrence (volume of the cyst <20% of the pre-operative volume), and 60% of the patients had significant recurrence (volume of the cyst >20% of the pre-operative volume). CONCLUSIONS: Percutaneous drainage of solitary kidney cysts for 24 h followed by injection of pure alcohol, as a sclerotic agent, is an effective therapeutic method with only a few complications. It was therefore considered being the proffered method for the treatment of solitary kidney cysts.
