[The complications of transurethral operations (an analysis of 5-year results)]. / Oslozhneniia transuretral'nykh operatsii (analiz 5-letnikh rezul'tatov).

Based on analysis of 309 transurethral [correction of transureteral] surgeries performed on patients with various diseases (prostatic adenoma, prostatic carcinoma, vesical tumors, urethral stenosis, cervical sclerosis) the authors scrutinized various complications: intraoperative (hemorrhages, vesical perforations) and postoperative ones. The most common postoperative complications were acute pyelonephritis, (5.82 per cent), dysuria (3.88), urethral stenosis (2.91 per cent). Immediate and long-term postsurgical hemorrhages were documented in 4.2 per cent and enuresis in 1.94 per cent of the patients. Certain prophylactic measures were considered. The duration of surgery was found to be correlated with the incidence of postoperative complications and it should not exceed 30-49 min. The mortality rate was 1.29 per cent.

[Urodynamics of the lower urinary tract in patients with prostatic adenoma and cancer before and after transurethral surgery]. / Urodinamika nizhnikh mochevykh putei u bol'nykh adenomoi i rakom predstatel'noi zhelezy do i posle transuretral'nykh operatsii.

Combined urodynamic investigation, including uroflowmetry, cystomanometry and intraurethral pressure profile (IPP) assessment, was carried out in 25 patients with prostatic adenomas and carcinomas, selected to undergo transurethral electroresection (TUR). The same combined investigation was repeated 2 months after TUR in 14 of 25 patients. The study of lower urinary urodynamics made use of Diza-2100 (Denmark) measuring system, recording maximum and mean volumetric urinary flow rate, volume and duration of micturition. The quantity of residual urine was also determined; the bladder was filled with CO2 at the rate of 50 ml/min for retrograde cystomanometry. In IPP assessment, the rate of catheter removal from the bladder was 1 mm/sec, and the rate of gas perfusion was 10 ml/min. Post-TUR follow-up revealed an increase of volumetric micturition rate to normal values, a drop in maximum intravesical pressure, and a reduction of functional length of the urethra and its prostatic segment, demonstrating that TUR is a very effective method of treatment for prostatic adenomas and carcinomas, involving little injury, and that the examined parameters of lower urinary urodynamics are objective indicators of treatment efficiency.
