Female urethra-sparing cystectomy and orthotopic bladder replacement.

OBJECTIVE: Orthotopic bladder replacement after cystoprostatectomy has long become the method of choice in the treatment of infiltrating bladder cancer in males. Very good quality of life in patients thus treated stimulated the work on a similar approach applicable to females. METHODS: Twelve females were treated by urethra-sparing cystectomy. The surgical technique preserves not just the urethra itself but also the pelvic floor and relevant innervation. RESULTS: Diurnal continence was achieved in 11 patients, 1 of whom had a so-called hypercontinence with a residual volume of 300 ml. The remaining patient suffered from stress incontinence. CONCLUSION: The described urethra-sparing radical cystectomy in female patients with a urothelial tumor, with normal pelvic floor and with a low risk of secondary affection of the urethra, permits reconstructing a continent orthotopic neobladder from a detubularized intestinal segment.

[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.

[Interstitial cystitis].

Interstitial cystitis (IC) is a complex of painful mictional symptomatology of unknown etiology. Is occurs more frequently in women. By cystoscopy the ulcerative and non-ulcerative form is differentiated. A typical diagnosis symptom are glomerulations during cystoscopy under general anaesthesia. There are diagnostic criteria which rule out IC. Histopathologically the following are differentiated: classical IC with proliferation of mastocytes in the detrusor, detrusor myopathy and eosinophil cystitis. Treatment includes intervesical instillation of various substances, transurethral procedures or supratrifonal cystectomy, incl. enterocystoplasty.
