TURP Outcome Prediction Calculator Study

Benign Prostatic Hyperplasia (BPH)

BPH, LUTS, TURP, Uroflowmetry, IPSS, Outcome Prediction

The goal of this observational study is to identify which preoperative clinical, ultrasound, and uroflowmetry parameters can help predict the success of transurethral resection of the prostate (TURP) in adult male patients with symptomatic benign prostatic hyperplasia (BPH). The main questions it aims to answer are: Which preoperative parameters (IPSS, prostate volume, post-void residual urine, Qmax, comorbidities) are associated with successful postoperative outcomes? Can these parameters be used to develop a non-invasive calculator to estimate the likelihood of TURP success? Participants will undergo routine clinical evaluation that is part of standard care, including: * completion of the IPSS questionnaire * digital rectal examination * ultrasound measurement of prostate volume and residual urine * uroflowmetry (Qmax and voided volume) * standard laboratory testing Eligible participants will then undergo TURP as clinically indicated and return for postoperative assessments of symptom improvement and urinary flow parameters.

Benign prostatic hyperplasia (BPH) is a common condition in aging men and may lead to lower urinary tract symptoms (LUTS), subvesical obstruction, and related complications such as urinary retention, bladder stones, recurrent infections, and renal impairment. Transurethral resection of the prostate (TURP) remains the standard surgical treatment for symptomatic benign prostatic obstruction (BPO). However, a subset of patients, particularly those with an underlying hypocontractile detrusor, may not benefit from TURP and continue to experience significant voiding dysfunction after surgery. Since formal urodynamic pressure-flow studies are invasive, time-consuming, and resource-intensive, there is clinical value in identifying non-invasive predictors of surgical success. This prospective observational study will evaluate preoperative clinical, ultrasound, and uroflowmetry parameters associated with successful postoperative outcomes after TURP. Adult male patients with symptomatic BPH and an indication for TURP will undergo standardized assessment including medical history, IPSS questionnaire, digital rectal examination, serum PSA, ultrasound-determined prostate volume and post-void residual urine, and uroflowmetry parameters such as Qmax and voided volume. Comorbidities relevant to bladder function, including diabetes mellitus and neurological conditions, will be recorded. TURP will be performed according to standard clinical practice, and resected tissue will undergo routine histopathological evaluation. Postoperative follow-up will include IPSS reassessment, uroflowmetry, and ultrasound measurement of residual urine at one month and during subsequent routine evaluations. Surgical outcomes will be categorized as successful or unsuccessful based on subjective symptom improvement and objective urinary flow parameters. Using the collected data, the study will identify which preoperative variables correlate with favorable postoperative outcomes. These parameters will subsequently be used to inform the development of a predictive TURP outcome calculator. The anticipated value of this study is to support individualized clinical decision-making in patients with BPH, particularly those in whom the distinction between obstruction and impaired detrusor contractility is unclear. By identifying patients who are less likely to benefit from TURP based on non-invasive parameters, the resulting calculator may help reduce unnecessary procedures, avoid postoperative morbidity, and potentially limit the need for invasive urodynamic testing.
