Suprapubic Drainage During Transurethral Cystolithotripsy for Large Bladder Stones (SPT-CYSTO Tria)
Transurethral Cystolithotripsy With Versus Without Adjunctive Suprapubic Tube Drainage for Bladder Stones >2 cm: A Prospective Randomized Controlled Trial
Bladder stones larger than 2 cm are commonly treated by endoscopic fragmentation through the urethra. During transurethral cystolithotripsy for large stones, the procedure may be prolonged because of poor visibility, stone dust, bladder overdistension, and repeated need for irrigation or evacuation.
This randomized controlled trial will compare standal Holmium:YAG laser cystolithotripsy using a 17 Fr cystoscope sheath with the same procedure plus an adjunctive 8 Fr suprapubic catheter used only for bladder drainage during the operation. The suprapubic catheter will not be used for stone fragmentation or stone extraction.
The main outcome will be total operative time. Secondary outcomes will include fragmentation and clearance time, laser activation time, total laser energy, irrigation volume, visibility-related interruptions, stone-free rate at 30 days, complications, catheter duration, postoperative pain, and hospital stay.

상세 설명
This is a prospective, randomized, controlled, parallel-group clinical trial conducted at the Department of Urology, Beni-Suef University Hospital, Faculty of Medicine, Beni-Suef University, Egypt. Adult patients with radiologically confirmed bladder stones greater than 2 cm who are scheduled for elective transurethral cystolithotripsy will be enrolled after written informed consent.
Participants will be randomized in a 1:1 ratio into two groups. The control group will undergo standardized transurethral Holmium:YAG laser cystolithotripsy using a 17 Fr cystoscope sheath with conventional irrigation and transurethral evacuation only. The experimental group will undergo the same procedure with adjunctive 8 Fr suprapubic catheter drainage inserted under ultrasound guidance and cystoscopic visualization. The suprapubic catheter will be connected to free drainage during lithotripsy to assist bladder decompression and irrigation outflow. It will not be used for stone fragmentation, stone extraction, tract dilation, sheath placement, or percutaneous cystolithotripsy.
All procedures will use the same standardized cystoscopic access, Holmium:YAG laser platform, irrigation system, and transurethral evacuation method. The primary outcome is total operative time, measured from cystoscope insertion into the urethra until endoscopic confirmation of complete stone clearance and completion of final urethral catheter placement. Postoperative follow-up will continue for 30 days, including assessment of stone-free status by imaging and recording of perioperative complications.

활성 비교기: Standard Transurethral Cystolithotripsy
Participants assigned to this arm will undergo standardized transurethral Holmium:YAG laser cystolithotripsy using a 17 Fr cystoscope sheath with conventional irrigation and transurethral evacuation only, without adjunctive suprapubic catheter drainage.
|
Standardized transurethral Holmium:YAG laser cystolithotripsy performed through a 17 Fr cystoscope sheath, with conventional irrigation and transurethral evacuation of stone dust and fragments.
A urethral Foley catheter will be inserted at the end of the procedure.
This procedure will be performed in both study arms.

실험적: Transurethral Cystolithotripsy With Suprapubic Drainage
Participants assigned to this arm will undergo the same standardized transurethral Holmium:YAG laser cystolithotripsy using a 17 Fr cystoscope sheath, with adjunctive 8 Fr suprapubic catheter drainage inserted under ultrasound guidance and cystoscopic visualization for bladder drainage and decompression during lithotripsy.
No stone fragmentation or extraction will be performed through the suprapubic route
|
Insertion of an 8 Fr suprapubic catheter under ultrasound guidance and cystoscopic visualization during transurethral cystolithotripsy.
The catheter will be connected to free drainage to assist bladder decompression and irrigation outflow during lithotripsy.
It will not be used for stone fragmentation, stone extraction, tract dilation, sheath placement, or percutaneous cystolithotripsy.

Total Operative Time
기간: During the surgical procedure
|
Total operative time will be measured in minutes from insertion of the cystoscope into the urethra until endoscopic confirmation of complete bladder stone clearance and completion of final urethral catheter placement.
In the suprapubic drainage group, the time required for insertion of the 8 Fr suprapubic catheter will be included because the study evaluates the overall procedural efficiency of adding adjunctive suprapubic cathe+ drainage
