In a retrospective study, the complications of vesical drainage after gynaecological surgery in 2362 cases was analysed. The suprapubical catheter was found to cause less urinary tract infection than the dwelling transurethral catheter. Less intermittent recatheterisation, owing to vesical emptying disorders, was needed after suprapubical catheter. Due to frequent obstruction, the suprapubical catheter had to be removed earlier in some cases. In this study urinary tract infection was more frequently observed after vaginal hysterectomy than abdominal. Regarding the incidence of microorganisms in the urine, we found, that after Caesarean section Staph. epidermidis occurred more frequently, whereas E. coli prevailed in most of the other cases.

Long-term use of a widely available oestrogen-containing hair lotion caused specific systemic oestrogen effects with proliferation of the endometrium in two patients aged 66 and 82 years. Uterine bleeding was the cardinal sign. These findings confirm the possible percutaneous absorption of externally applied oestrogen-containing substances. They probably also explain an oestrogen effect on uterine epithelium, which is not rarely seen during cancer-preventive gynaecological examination and has no other explanation.
