The value of urodynamic examination in treating the patient with prostatic hyperplasia accompany with dysfunction of the bladder

Objective To investigate the value of urodynamic in treating those patients with benign prostatic hyperplasia complicated with bladder dysfunction. Methods 130 patients with benign prostatic hyperplasia were retrospectively reviewed between December 2015 and December 2016. The exclusive criteria included nervous system diseases, moderate to severe diabetes, moderate to severe hypertension, urethral stricture, bladder stones, prostate cancer, etc. The patient's age is ranged 51 to 92, mean 72 years old. The previous history of disease ranged from 3 months to 15 years, mean 4 years. All patients accepted the urodynamic examination. Different treatments were considered according to urodynamic studies. Results According to the classification of bladder outlet obstruction, 130 cases were classified as bladder outlet obstruction in 109 cases, bladder suspicious obstruction in 15 cases, no bladder obstruction in 6 cases. According to the classification of bladder function, 130 cases were divided into unstable bladder in 6 cases, low compliance bladder in 7 cases, bladder atony in 15 cases, bladder without tension in 3 cases, normal bladder function in 99 cases. 3 cases without bladder tension, including BOO in 2 cases, suspected BOO in 1 case, were accepted the cystostomy. 15 cases with less detrusor contraction, including BOO in 4 cases, suspected BOO in 9 cases, were accepted the cystostomy and TURP. Conservative treatment was performed in other 2 cases without obstruction. In 6 cases with unstable bladder, 2 cases without obstruction accepted the conservative treatment, 4 cases with suspected BOO accepted the TURP. In 7 patients with low compliance bladder, 2 cases without obstruction accepted the conservative treatment, 5 cases with suspected BOO accepted the TURP. The duration of following up was 3-6 months. The symptoms of the patients in this group improved significantly during following up. Conclusion For patients with benign prostatic hyperplasia complicated with bladder dysfunction, the results of urodynamics can help to choose the right treatment and improve effect of treatment.
