ABSTRACT
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.

Se realizaron 1.127 endoscopias en el periodo comprendido desde marzo de 1977 hasta octubre de 1979 en el Hospital Universitario "Americo Boavida" de Luanda.Se selecciona para el estudio 690 (61.1
) endoscopias con diagnostico de schistosomiasis vesical. Se encuentran como lesiones mas frecuentes los huevos calcificados del parasito y la mucosa vesical deslustrada, signos de cronicidad que alertan sobre lo tardiamente que acuden a las consultas de urologia los pacientes portadores de esta enfermedad en el medio estudiado
