Intestinal resection can lead to decreased gastrointestinal absorption of various metabolic substances. The use of these intestinal segments as materials for urinary tract reconstruction can also induce metabolic disorders. The authors studied the long-term metabolic consequences of replacement enterocystoplasty after radical cystectomy for bladder cancer.

OBJECTIVE: To evaluate the efficacy and morbidity of treatment of localized prostatic cancer using transrectal high-intensity focused ultrasound. MATERIAL AND METHODS: 44 patients (mean age: 72 years) with clinical stage T1 (20) or T2 (24) prostatic cancer, not eligible for radical prostatectomy, were treated by two different prototypes of the Ablatherm (Technomed Medical System). The second prototype includes several safety devices designed to reduce morbidity. 99 sessions were performed, i.e. an average of 2.25 sessions per patient: the prostate was treated in one session (5 patients), 2 sessions (26 patients), 3 sessions (10 patients), or 4 sessions (3 patients), usually under spinal anaesthesia. The mean PSA was 9.92 ng/ml and the mean prostatic weight was 37 g. RESULTS: Complications occurred in 10 (50%) of the first 20 patients treated (1993-1995): 2 recto-urethral fistulas, 2 asymptomatic rectal burns, 2 cases of stable urinary retention, 1 case of severe incontinence, 3 cases of bladder neck sclerosis, and 1 febrile urinary tract infection. In the 24 patients treated subsequently (1995-1997), complications occurred in only 4 patients (16%): 1 case of stable urinary retention, 1 febrile urinary tract infection, 1 case of bladder neck sclerosis, 1 case of stress incontinence. A complete response (repeated negative follow-up biopsies) was obtained in 27 patients (61%). The mean post-treatment PSA level in patients of this group was 1.09 +/- 1.06 and remained stable (mean follow-up: 346 days; range: 60-1250). A residual cancer was detected in 17 patients (39%). 8 patients were considered to be failures (mean post-treatment PSA: 4.8 ng/ml) and received adjuvant treatment (hormonal: 3; external radiotherapy: 5). Complementary treatment by focused ultrasound will be performed in another 9 patients, if their PSA rises above 3 ng/ml (patients of this group are symptomatic with a mean post-treatment PSA of 1.6 ng/ml). CONCLUSION: The morbidity of treatment by transrectal focused ultrasound has now been reduced. These results suggest that this new treatment can constitute a useful option for certain patients with localized cancer, not suitable for radical prostatectomy.

[Use of the Valtrac ring for digestive anastomoses in urology: apropos of 16 cases]

The Valtrac ring is a biofragmentable ring used for gastrointestinal anastomoses. Over a two-year period, 15 anastomoses in 16 patients (mean age: 60 years) were performed with the Valtrac ring: 10 ileal, 4 ileocolonic, and 1 jejunojejunal anastomoses. One anastomosis could not be performed because of an excessively narrow ileal lumen. The mean stay in the intensive care unit was 3 days: gastric aspiration was maintained for an average of 1 week, as return of gastrointestinal motility was long, with first flatus on the 6th day and the first stools on the 7th day. Complications consisted of 2 cases of gastrointestinal fistula (11th and 13th days) one of which was fatal, evisceration on the 7th day, a transient partial bowel obstruction and one bowel obstruction treated medically on the 27th day, due to pancreatitis. Our results are not identical to those reported in the literature. It is often difficult to insert the current form of the Valtrac ring into a healthy ileum, as the smallest ring is often too large. In contrast with gastrointestinal surgery, the anastomoses performed in urology involve a non-thickened, non-distended small intestine.
