Application urodynamic indicators transurethral resection (TURP) transurethral resection (TUVP) after prostatic hyperplasia (BPH) patients with detrusor function changes for research, evaluation of bladder function recovery , and thereby observe BPH and functional changes in the bladder detrusor between . 47 cases of BPH patients ( mean age 68.5 years , mean follow-up time of 6.95 months ) OK TURP TUVP surgery were preoperative and postoperative IPSS and urodynamic studies , and analyzed statistically . Postoperatively compared with preoperative , IPSS score decreased to 10.62 from the 25.33 points points , maximum flow rate of 6.89ml / s up to 17.26ml / s, detrusor pressure at maximum flow rate from the 82.31cmH2O (32 cases) decreased to 41.25cmH2O (26 cases) , suggesting obstruction be lifted ; bladder compliance increased by the 23.26ml/cmH2O 43.51ml/cmH2O, initial urine volume increased from preoperative 72.93ml to 102.62ml, the largest increase in urine volume by the 263.56ml to 356.58ml, tips bladder function was restored ; bladder compliance , the initial urine volume , the maximum volume of urine before and after surgery are different. The resulting TURP TUVP can realistically due to the cancellation of benign prostatic hyperplasia bladder outflow obstruction , restore bladder motor and sensory function, and the effect is stable ; benign prostatic hyperplasia bladder outlet obstruction resulting detrusor instability occurs first l high , contractility, compliance, further development of the compliance increased, decreased contractility . Urodynamics can effectively assess detrusor function, BPH diagnosis and preoperative prediction of postoperative complications , surgical indications and choice of surgical approach has important significance.
