[A continent urinary diversion with a detubularized rectum and sigmoid (sigmo-rectal pouch)].

BACKGROUND: The continent reservoir is an ideal urinary diversion in patients after cystectomy. The artificial closing mechanism construction in these reservoirs is rather complicated and the results are uncertain. The objective of the present work is to assess own experience with a relatively simple rectosigmoid reservoir created by a method described by M. Fisch. METHODS AND RESULTS: Since 1992 till 1995 the sigma-rectum detubularized reservoir was performed in 30 patients. The intricating bladder cancer was an indication for the operation in 27 patients and the other bladder diseases in 3 patients. The patients age ranged from 18 to 75 years. Diurnal continence was achieved in all 30 patients. 12 of them have to awake during the night to evacuate the reservoir 1 to 3 times. CONCLUSIONS: Sigma-rectum pouch is a good form of cintinent diversion in such patient, which are not suitable for orthoscopic neobladder because of oncologic limitation or bad general conditions. The patients tolerate the procedure very well, heal and adapt quickly to new evacuating mechanisms.

[Orthotopic reconstruction of the urinary bladder with preservation of urethral function in women after cystectomy].

Since 1993 till 1995 cystectomy preserving the urethra in twelve female patients with infiltrating bladder cancer was performed. The patients age ranged form 32 to 72 years. The female urethra sparing radical cystectomy includes removal of the bladder together with the uterus and ovaries and resection of the anterior vaginal wall. The condition for preserving of the function of the urethra is its integrity including corresponding innervation and intact pelvic floor. The neobladder is made of a detubularized ileal segment and anastomosed with the urethra. Diurnal continence was achieved in 11 patients, one of them has so called hypercontinence with residual volume of 300 ml. One patient suffers from stress incontinence. The functional characteristics of the orthotopic neobladder in the operated females are very favourable. The risk of further affliction of the retained urethra with an urothelial tumor is possible to influence by a choice of selected patients for the overmentioned procedure.

[A continent artificial urinary bladder from detubulized ileal or ileocecal segments].

At present, the attention of reconstructive surgery is focused on continent reservoirs constructed from detubulized intestinal segments. Based on two-year experience, the authors present an analysis of the results obtained from 26 patients with continent ileal or ileocecal neovesica. These operations improve the quality of life and guarantee more safety. In most cases, the function of the neovesica approximates the natural physiological condition. The authors also discuss the economical aspect as regards the high cost of materials needed for ureteroileostomy--annual expenditure on flanges and bags (firm Pfizer) per 1 person amounts to 32,000 Czechoslovak crowns fco. The continent neovesica does not narrow the therapeutical spectrum of urinary deviations, on the contrary, it extends them, which is why the authors prefer to use it.

[Diagnosis of pelvic lymph node involvement in carcinoma of the prostate].

In 64 patients with prostate carcinoma localized on a gland or pelvic lymph nodes the authors evaluated the possibility of non-surgical assessment of lymphatic metastases. The results were compared with conclusions of histological examination of the nodes obtained by pelvic lymphadenectomy. The stage and histological classification of primary prostate disease correlates to a certain extent with affection of the nodes. The serum levels of ACP and ACPT are elevated in some of the patients with metastases in the pelvic lymph nodes. Both these method enable us to make certain predictions, in particular when the methods are used in combination. However, they cannot replace lymphadenectomy completely. The reliability of bipedal lymphography is 26.4%. Therefore this method, similarly as isotope lymphography, is quite inadequate for evaluation of the condition of the lymphatic system.
