A Comparative Study Between Anterior and Posterior Pyelotomy in Transperitoneal Laparoscopic Pyelolithotomy

April 30, 2024 updated by: Damascus University

Transperitoneal Laparoscopic Pyelolithotomy: Is the Posterior Pyelotomy Better Than the Anterior? (A Randomized Controlled Clinical Trial)

Large renal pelvic stones are frequently managed with percutaneous nephrolithotomy (PCNL) but laparoscopic pyelolithotomy (LPL) can be an alternative procedure when performed by skilled surgeons to achieve excellent outcomes in terms of stone free status, operative time, postoperative kidney function, hospitalization duration, and complications.

there are two methods for LPL surgery : Transperitoneal (TLP) and Retroperitoneal (RLP).

RLP associated with shorter mean time for oral intake, and mean hospital stay after surgery.

The surgical exposure in the transperitoneal route for LP is familiar to the majority of surgeons. Also, a much larger working space is available and there are various established anatomical landmarks for performing the surgery effectively. This study introduces a modified technique that creates application of posterior pyelotomy in TLP to achieve the advantages of RLP

Study Overview

Detailed Description

This is a randomized controlled clinical trial that aims to collect a sample within two years from the date of approval of the Scientific Research Council at Damascus University.

The study will focus on a group of patients who will undergo a transperitoneal laparoscopic pyelolithotomy surgery.

The patients will be randomly divided into two groups. The first group will undergo a traditional transperitoneal laparoscopic pyelolithotomy, which involves application of anterior pyelotomy.

The second group will receive a modified transperitoneal laparoscopic pyelolithotomy, which involves application of posterior pyelotomy.

The data will be compared between the two groups in terms of the mean duration of surgery ,mean time for oral intake ,and mean hospital stay

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Operative time
Time Frame: at the end of surgery in the operating room

the duration of the surgical procedure. It is measured by minutes, and calculated from establishing the pneumoperitoneum until the surgery is completed by suturing the skin.

It will be measured in the outcome by the mean

at the end of surgery in the operating room
Days for oral intake
Time Frame: Up to one week after surgery

the number of days to start introducing oral fluids and food after surgery with good acceptance, and without vomiting or flatulence.

It will be measured in the outcome by the mean

Up to one week after surgery
Days of hospital stay
Time Frame: up to ten days after surgery
the number of days the patient stayed in the hospital after surgery. It will be measured in the outcome by the mean
up to ten days after surgery
Postoperative urine leak
Time Frame: up to three days after surgery

considered to be present when the drain contained >30 cc of urine the morning after surgery.

It is measured by answering the question: Is there any urinary leakage, yes or no? It will be measured in the outcome by the ratio

up to three days after surgery
stone-free status
Time Frame: Up to one week after surgery
postoperative radiological imaging demonstrating evidence of residual stones It will be measured in the Outcome by the ratio
Up to one week after surgery
