Treatment for benign prostatic enlargement (BPE) should involve adequate and steady control of lower urinary tract symptoms (LUTS). TURP has gained enormous popularity over the past years, and this surgical treatment of BPE improves bothvoiding and storage symptoms. However, a large proportion of patients complain of persistent storage symptoms following TURP. Although TURP could relieve storage symptoms, there is a definite limitation on the clear satisfaction of symptom improvement, and clinicians should consider whether early use of medications such as anticholinergics could help in the treatment of storage symptoms. In this study, authors tried to investigate the association betweenvarious preoperative clinical parameters and remaining postoperative storage symptoms following TURP. From this analysis, they aimed to clarify valuable prognostic factors regarding the persistence of storagerelated symptoms following BPE-related surgery. In study all patients completed the International Prostate Symptom Score (IPSS) with a subscore for storage symptoms (questions 2, 4 and 7). Patients underwent the following basic clinical evaluations: prostate volume estimated by transrectal ultrasound, functional bladder capacity (FBC) and voiding frequency per day urodynamics were also assessed, including Q max (maximum flow rate), postvoid residual urine estimated by ultrasound, maximum cystometric capacity, detrusor pressure at maximum flow (Pdet Q max) and Abrams-Griffith number (Pdet Q max- 2 × Q max). In this study, initial storage symptom score, age, FBC and BCI were identified as independent predictors for an improvement in storage symptoms. The authors concluded that Positive and consistent correlations between the baseline degree of worse initial storage symptoms, bladder capacity, detrusor contractility and age and the improvement in storage symptoms were observed.
