Objective: To evaluate the urodynamic outcomes of transurethral resection of the prostate (TURP) in patients of benign prostatic enlargement (BPE) with upper urinary tract dilatation and correlate with International Prostate Symptoms Score (I-PSS). Methods: In this prospective study, patients of BPE with upper urinary tract dilatation from July 2017 to June 2019 were enrolled. At presentation, detailed I-PSS, ultrasonography abdomen, serum creatinine, and serum PSA were recorded. All the patients were catheterized and observed for postobstructive diuresis. At 4 weeks, repeat ultrasound and serum creatinine were recorded. Urodynamic study (UDS) was performed after ensuring sterile urine culture. Patients underwent TURP as per the standard technique. A repeat UDS was performed after 3 months, and analysis was done. Results: Forty-four patients were enrolled of which data of 37 patients were analyzed. In the filling phase of the UDS, there was a significant decrease in detrusor pressure at the end filling phase from 27 to 9.0 cm H[sub.2]O after TURP. Maximum cystometric capacity and bladder compliance significantly improved at 3 months following surgery. In the voiding phase, peak flow rate showed a significant increase, postvoid residual urine volume significantly decreased, and peak detrusor pressure marginally decreased following TURP. The I-PSS decreased from 20 ± 8 to 5 ± 6 following TURP. Conclusion: High detrusor pressure and reduced compliance is a risk factor for upper urinary tract dilatation. Changes in the bladder dynamics and resolution of hydronephrosis following TURP reflected in the changes in urodynamic parameters and I-PSS. Keywords: Transurethral resection of the prostate, Benign prostatic enlargement, Creatinine, Urodynamic study, Upper urinary tract dilatation
