OBJECTIVES: To evaluate the clinical and urodynamic characteristics of a series of adult males with BPH and @entity1494 , and to analyze the changes in urodynamics in @entity1 undergoing lower urinary tract surgery to relieve obstruction, with or without associated diverticulectomy. METHODS: We studied 91 @entity1 in two groups: Group 1- BPH: 67 cases (73.6%) and Group 2-BPH + diverticulum: 24 cases (25%). Mean age was 65.04 years. All @entity1 underwent urological physical examination and complete urodynamic study including cystogram. In addition, we studied 19 @entity1 with BPH and @entity1494 (mean age 64.58 years) who underwent either endoscopic surgery (1 I cases; 57.9%) or endoscopic surgery plus diverticulectomy (8 cases, 42. 1%). Complete clinical study and urodynamics (including cystogram) were performed preoperative and three months after surgery. Statistical significance was established at 0.05. RESULTS: Comparative study between group 1 (BPH) and group 2 (BPH with diverticulum): there were significant differences in clinical data: acute urinary retention (6.1% vs. 25%;p<0.01), and @entity293 (3.1% vs. 21.7%;p=0,004). All evaluated cases had single @entity7261 (8 cases). Urodynamic studies showed: 1) Post-void residual after free flowmetry: 45.9 ml vs. 221.4 ml, p = 0.008. 2) Bladder capacity on cystometrogram: 211.2 ml vs. 350.8 ml, p = 0.024. 3) Voiding pressure/flow study: a) Voiding with abdominal press 23.9% vs. 50%, p = 0.02. b) URA 36.5 cm @entity2507 vs. 48.5 cm @entity2507 , p= 0.04, c) post void residual 70.7ml vs. 210.3 ml, p= 0.004. d) Bladder contractility measurements (Wmax- isometric contractility- and @entity65550 , W20- isotonic contractility) did not show significant differences between groups. Bladder contractility duration was significantly decreased in group 2. In the analysis of @entity1 undergoing surgery to relieve obstruction (Group A- Surgery without diverticulectomy; Group B Surgery with diverticulectomy) there were not differences between groups in clinical data. Urethral resistance parameters (URA) decreased in both groups. Group A: from 43 cm H20 to 26.3 cm @entity2507 . Group B: from 60.6 cm @entity2507 to 48 cm @entity2507 . This decrease was similar after either TURP or myocapsulotomy. Post void residual diminished in both groups. There were no statistical differences between groups in Wmax, W 80-20, or volume, number and site of the @entity7261 . On the contrary, bladder contractility duration diminished after diverticulectomy. CONCLUSIONS: Bladder @entity7261 appear in the cases with highest ureteral resistance values (lower urinary tract obstruction). Standard bladder contractility parameters were not diminished. Duration of detrusor contraction was the only contractility parameter significantly affected in cases of @entity1494 and presented a significant association with the use of abdominal press while voiding. Diverticulectomy showed an improvement of bladder contractility with longer detrusor contraction duration, which supports its use in cases of @entity7261 . Both TURP and transurethral incision of the prostate diminished urethral resistance in a similar way, so that they may be considered alternative options. Our data should be confirmed with a bigger sample size.
