Endopyelotomy and pyeloplasty: face to face

Area of Science:

• Urology
• Surgical Techniques
• Nephrology

Background:

• Ureteropelvic junction (UPJ) obstruction affects symptomatic adult patients.
• Surgical intervention is often required to restore proper drainage.
• Pyeloplasty and endopyelotomy are common surgical approaches.

Purpose of the Study:

• To compare the technical aspects, complications, and outcomes of pyeloplasty versus endopyelotomy.
• To evaluate the effectiveness of each procedure in improving renal function and drainage patterns.
• To assess patient recovery and cosmetic results.

Main Methods:

• A comparative study of 46 adult patients with UPJ obstruction.
• Patients were randomized into two groups: pyeloplasty (n=23) and endopyelotomy (n=23).
• Outcomes were assessed using clinical parameters, complication rates, and 99Tc-DTPA diuretic scans.

Main Results:

• Endopyelotomy demonstrated shorter operating times and hospital stays with better cosmetic acceptance.
• Major complications for endopyelotomy included issues with external drainage, secondary infection, fever, hemorrhage, and tube slippage.
• Pyeloplasty complications involved prolonged urinary leak, wound infection, and urinary tract infection.
• No significant improvement in split renal function was observed in either group; function did not deteriorate.
• Both procedures resulted in comparable complication rates and successful drainage in most cases, with endopyelotomy showing a slight advantage.

Conclusions:

• Endopyelotomy is advantageous over pyeloplasty due to reduced operating time and hospital stay.
• Complication rates and surgical outcomes are comparable between the two procedures.
• While endopyelotomy offers benefits, early resumption of work was not achieved due to external drainage requirements.
