The effects of thiotepa, mitomycin C, BCG and interferon instillation on urothelium.

The effects of Thiotepa, Mitomycin C, BCG and Interferon on urothelium were researched in rabbits. Early changes of a contracted bladder such as fibroblastic atypia and sub-epithelial plaque were seen in all groups in different rates. This rate in the Thiotepa and BCG groups was 100% and in the Mitomycin C and Interferon groups 60%.

Urinary retention after renal and ureteric surgery.

A retrospective study was carried out on 200 patients who underwent surgery between January 1989 and September 1991. The aim was to investigate the development of urinary retention following renal and ureteric surgery. The incidence of urinary retention was 55% for patients in the renal group and 26% for those in the ureteric group.

Transvesical and transvaginal reparation in urinary vaginal fistulas.

Thirty-two cases of urinary vaginal fistulas treated surgically at our Department between 1985 and 1991 have been reviewed retrospectively. There were 26 cases of vesicovaginal fistulas, 1 case of urethrovaginal fistula and 5 cases of ureterovaginal fistulas. Gynaecological surgery was the leading cause of the fistulas (24/32).
