The aim of this clinical trial is to evaluate the effect of detrusor underactivity on the functional and symptomatic outcomes following transurethral resection of the prostate (TURP) in benign prostatic hyperplasia patients presenting with chronic urinary retention.

The main questions it aims to answer are:

Will they restore spontaneous voiding?

They will be divided into 2 comparative groups (each group 45 patients) based on detrusor contractility.

• Group (A) consists of patients with normal detrusor (bladder contractility index more than 100).
• Group (B) consists of patients with underactive detrusor (bladder contractility index less than 100).

Inclusion Criteria:

• Age: more than 50-year-old
• Chronic urinary retention secondary to BPH
• Prostate size Above 30 and less than 100gm

Exclusion Criteria:

• Prostate size over 100 gm and less than 30 gm
• Prostatic carcinoma
• Urinary bladder carcinoma
• Acute urinary retention
• Urethral stricture.
• Previous bladder, urethral or prostate surgery.
• Acute urinary tract infection.
• Neurogenic bladder
