Outcome Measures

Primary Outcomes (1)

  • stone free state

    The number of patients with no residual stone fragments with no need to shift to other modality or auxiliary maneuver

    1 week post operative

Study Arms (2)

Group A (Transurethal group)

EXPERIMENTAL

Patients will have trans urethral approach for management of their bladder stones. Either pneumatic or Holmium:YAG laser will be used for stone disintegration. Stone basket and/or Elics current evacuation will be used to retrieve stone fragments. Urethral catheter will be applied for 48 hours.

Procedure: Transurethral extraction of bladder stone(s)

Group B (Percutaneous group)

EXPERIMENTAL

Patients will have per cutaneous approach for management of their bladder stones. After initial cystoscopy a Foley's urethral catheter will be fixed for continuous irrigation. Then, the bladder will be filled to capacity with normal saline. Access to the distended bladder will be obtained by 10-gauge needle in the mid line 1-2 cm above the pubic bone. Once suitable placement is confirmed with return of fluid, a guide wire will be passed through the needle into the bladder. Dilatation will be done using 8-10 Fr coaxial dilators then single fascial dilator with placement of 16 Fr Amplatz sheath as a working tract. No ultrasonic or fluoroscopic guidance will be used. Stone basket will be used to extract the stone. If the stones were larger than the used sheath, disintegration will be performed with a pneumatic lithotrite. Primary skin closure of the suprapubic stab wound by one stitch will be done and the urethral catheter will remain for 48 hours.

Procedure: percutaneous extraction of bladder stone(s)
