Background: Benign prostatic hyperplasia (BPH) is the most common benign neoplasm in men. The present study was conducted to assess complications of transurethral resection of the prostate (TURP). Materials & Methods: 128 cases underwent transurethral resection of the prostate (TURP). Patients with lower urinary tract symptoms were clinically diagnosed by per rectal digital examination and transrectal ultrasonography. They were evaluated at 3 months for complications. Results: The age group 20-30 years had 14, 30-40 years had 46 and 40-50 years had 68 patients. Common complications were infection in 3 patients, bleeding in 15, injury of orifices in 5, urinary retention in 7, incontinence in 11, erectile dysfunction in 2 and recurrent BPH in 8 patients. The difference was significant (P< 0.05). Conclusion: Common complications were infection, bleeding, injury of orifices, urinary retention, incontinence, erectile dysfunction and recurrent BPH.
