Transperitoneal laparoscopic pyeloplasty: Brazilian initial experience with 55 cases

Area of Science:

• Urology
• Minimally Invasive Surgery
• Surgical Outcomes

Background:

• Ureteropelvic junction (UPJ) stenosis causes urinary obstruction and hydronephrosis.
• Conventional open pyeloplasty has been the standard treatment.
• Evaluating minimally invasive alternatives is crucial for improving patient outcomes.

Purpose of the Study:

• To prospectively assess the efficacy and safety of transperitoneal laparoscopic pyeloplasty.
• To compare the outcomes of laparoscopic pyeloplasty with traditional open surgical methods.
• To document complication rates and recovery times associated with laparoscopic pyeloplasty.

Main Methods:

• Prospective evaluation of 55 patients (13-64 years old) with UPJ stenosis treated between January 2005 and July 2009.
• Procedures included Anderson-Hynes dismembered pyeloplasty (51 patients) and Fenger technique (4 patients).
• Postoperative assessment involved clinical and imaging evaluations at 3, 6 months, and annually.

Main Results:

• The overall success rate was 95.65%.
• Mean operative time was 95-270 minutes, with a mean hospital stay of 2 days.
• Complications included urinary fistula (1 patient), portal infection (3 patients), prolonged ileus (6 patients), and re-stenosis (2 patients).

Conclusions:

• Laparoscopic pyeloplasty achieves functional results comparable to open surgery.
• This technique offers reduced morbidity, improved aesthetics, and faster convalescence.
• Laparoscopic pyeloplasty presents a favorable option with lower complication rates.
