Shock Wave Lithotripsy Versus Visual Cystolitholapaxy in The Management of Patients Presenting With Calcular Acute Urinary Retention: A Randomized Controlled Trial.

Shock Wave Lithotripsy Versus Visual Cystolitholapaxy in The Management of Patients Presenting With Calcular Acute Urinary Retention: A Randomized Controlled Trial.

The aim of the study is to compare the safety and efficacy of ESWL and visual cystolitholapaxy in management of calcular acute urine retention.

Patients who present with acute urinary retention due to stone in the urethra or urinary bladder will be randomly assigned to receive treatment either by extracorporeal shock wave lithotripsy or by endoscopic visual cystolitholapaxy where patients and stone characteristics will be recorded and the outcome including the intraoperative and postoperative complications and the stone free rate will be also evaluated

Inclusion Criteria:

1. Adult male patients presenting with acute urinary retention due to urethral or urinary bladder stones.
2. with a stone size not more than 2 centimeters in greatest diameter.
3. No more than 2 stones.

Exclusion Criteria:

1. Bladder cancer.
2. Bladder replacement of any type.
3. Infravesical obstruction, due to marked benign prostatic hyperplasia, prostate cancer, stricture urethra or external urethral meatal stenosis.
