[Faulty voiding and drinking habits--a contribution to the genesis of enuretic syndrome?].

In 122 children (85 girls, 37 boys) with nocturnal enuresis, information on drinking and voiding patterns was elicited. Many of them (60% of the girls and 40% of the boys) had previously been continent for 1-5 years. It turned out that the children tried to suppress voiding and had the habit of drinking primarily during the second half of the day. After changing these habits, 119 children became permanently continent.

The continent ileal bladder for urinary tract reconstruction after cystectomy: a survey of 44 patients.

The continent ileal bladder is an ileal pouch that is anastomosed to the urethral stump for urinary diversion after radical cystectomy. The ureters are implanted by an antireflux nipple ureteroileostomy. We report our results in 44 patients who underwent this type of diversion. The perioperative morbidity and mortality were comparable to those of an ileal conduit diversion. Urodynamic evaluation showed the ileal bladder to be a low pressure reservoir with a capacity that increased to more than 300 ml. The ileal bladder was emptied by straining without significant residual urine in all patients. After a training period of a few months all patients were continent in the daytime. However, some patients required pads at night because of occasional loss of urine.

[Urinary diversion following radical cystectomy: ileal conduit or ileal replacement bladder?].

Among those patients who have undergone radical cystoprostatectomy in the Department of Urology at the Municipal Hospital of Kassel (FRG) since 1985, 57 received a continent ileal bladder anastomosed to the membranous urethra. In a retrospective study intra- and postoperative complications, late complications and prognosis of the tumor disease of these patients were compared with those who had an ileum conduit from 1983 to 1988 (n = 44). The intra- and postoperative complications were nearly identical. During the further postoperative course, patients with a continent ileal bladder may present with strictures at the anastomosis of the ileal bladder and urethra, incomplete voiding with residual urine, secretion of water by the mucosa, and metabolic disturbances because of absorption of substances usually eliminated with the urine. The latter decreases with time as the glandular epithelium of the ileal mucosa changes into mucigenous cells with villous atrophy. The danger of local tumor recurrence and metastasis is the same in patients with an ileal bladder and an ileal conduit.

[Ureter replacement operations].

Reviewing the recent literature and own clinical experiences, the possibilities of replacement of the ureter by isolated bowel segments, alloplastic prostheses and xenoplastic or autoplastic transplants are shown and evaluated. Although used only in single cases, the interposition of the appendix vermiformis into larger defects of the ureter seems to render the best results. The interposition of bowel segments in the urinary tract has been applied more often, the results, however, have been variable. Numerous modifications have been proposed. The use of alloplastic prostheses and free autologic transplants have--up to now--led to no satisfying long-term results. Only human deep frozen umbilical veins as xenotransplants seem to be suitable as ureter replacements.
