Supine vs. Prone PCNL for Large Renal Stones: A Randomized Trial in Yemen.
Comparative Evaluation of Early Postoperative Complications, Cost-Effectiveness, and Patient-Centered Outcomes Following Supine and Prone Standard Percutaneous Nephrolithotomy (PCNL): A Randomized Controlled Trial
The goal of this clinical trial is to compare the safety, cost-effectiveness, and patient recovery of two different surgical positions for percutaneous nephrolithotomy (PCNL) in adults aged 18 to 70 years who have kidney stones larger than 2 cm. The main questions it aims to answer are:
- Does the supine (lying on the back) surgical position result in fewer early postoperative complications than the traditional prone (lying on the stomach) position?
- Does the supine position reduce the total surgery time, direct hospital costs, and postoperative pain?
Researchers will compare patients assigned to undergo PCNL in the supine position to those assigned to the prone position to see if the supine approach offers a safer, more cost-effective, and more comfortable recovery.
Participants will:
- Undergo standard PCNL surgery to remove their kidney stones in either the supine or prone position.
- Have their pain levels, surgery time, and any early surgical complications monitored during their hospital stay.
- Complete brief questionnaires regarding their overall surgical satisfaction and quality of life at 1 month and 3 months after the procedure.

Deltagargrupp / Arm |
Intervention / Behandling |
|---|---|
|
Aktiv komparator: Supine PCNL
Patients will undergo standard percutaneous nephrolithotomy (24-30 Fr tract size) performed in the supine position.
|
Standard PCNL performed with the patient in the supine position using a standard 24-30 Fr tract.
|
|
Aktiv komparator: Prone PCNL
Patients will undergo standard percutaneous nephrolithotomy (24-30 Fr tract size) performed in the conventional prone position.
|
Standard PCNL performed with the patient in the traditional prone position using a standard 24-30 Fr tract.

Primära resultatmått
Resultatmått |
Åtgärdsbeskrivning |
Tidsram |
|---|---|---|
|
Incidence and Severity of Early Postoperative Complications
Tidsram: Up to 30 days post-surgery
|
Complications will be assessed and classified using the Modified Clavien-Dindo Classification system.
The scale ranges from Grade I (minor deviation from normal postoperative course) to Grade V (death of the patient).
Lower grades indicate a better outcome.
|
Up to 30 days post-surgery
|
Sekundära resultatmått
Resultatmått |
Åtgärdsbeskrivning |
Tidsram |
|---|---|---|
|
Total Operative Time
Tidsram: Intraoperative (Day 0)
|
Total duration of the surgical procedure, measured continuously from the initial skin incision to the final skin closure, recorded in minutes.
|
Intraoperative (Day 0)
|
|
Direct Hospitalization Costs
Tidsram: From hospital admission to hospital discharge (typically 1 to 7 days)
|
Total direct medical costs associated with the procedure, calculated as the sum of disposable medical supply costs and hospital stay duration costs.
Measured in Yemeni Rials (YER).
|
From hospital admission to hospital discharge (typically 1 to 7 days)
|
|
Postoperative Pain Score
Tidsram: At 6 hours, 12 hours, and 24 hours post-surgery
|
Postoperative pain will be evaluated using the Visual Analog Scale.
The scale ranges from 0 (no pain) to 10 (worst imaginable pain).
Lower scores indicate a better outcome (less postoperative pain).
|
At 6 hours, 12 hours, and 24 hours post-surgery
|
|
Health-Related Quality of Life (HRQoL)
Tidsram: At 1 month and 3 months post-surgery
|
Measured using the EuroQol 5-Dimension 5-Level (EQ-5D-5L) questionnaire.
The utility index score will be calculated using the Kingdom of Saudi Arabia value set, ranging from -0.683 (worst possible health state) to 1.000 (full health), where higher scores indicate a better outcome (better health-related quality of life).
|
At 1 month and 3 months post-surgery
|
|
Patient Satisfaction Score
Tidsram: At 30 days post-surgery
|
Overall patient satisfaction with the surgical experience, anesthetic process, and early recovery will be measured using a 5-point Likert-type satisfaction scale.
The scale ranges from 1 (highly dissatisfied) to 5 (highly satisfied), where higher scores indicate a better outcome (greater patient satisfaction).
|
At 30 days post-surgery
