Abstract

PURPOSE:

Laparoscopic pyeloplasty was developed as a minimally invasive alternative to an open procedure for the treatment of ureteropelvic junction obstruction. Long-term followup has not yet been reported. We present experience with the first 100 consecutive cases of laparoscopic pyeloplasty performed at our institution.

MATERIALS AND METHODS:

A retrospective review of 100 consecutive laparoscopic pyeloplasties in 99 patients (means age 37.3 years) between August 1993 and January 1999 was performed. All patients had radiographic evidence of obstruction with signs, symptoms or deterioration of renal function. Repair was for primary ureteropelvic junction obstruction in 83 patients and secondary obstruction in 17. The 4 types of repairs performed were Anderson-Hynes dismembered (71 cases), Y-V plasty (20), Heineke-Mirhulicz (8) and Davis intubated ureterotomy (1). Type of repair used was dictated by intraoperative findings. Twenty patients had nonobstructing renal stones and underwent concomitant pyelolithotomy. All patients were assessed for symptoms and radiographic evaluation for anatomical obstruction.

RESULTS:

Average operating room time was 4.2 hours, which decreased with surgeon experience. Average blood loss was 181 cc and hospital stay was 3.3 days. Two patients required blood transfusion. A crossing vessel was found in 57 patients. With a mean clinical and radiographic followup of 2.7 and 2.2 years, respectively, 96% of the patients were free of obstruction on followup radiographic imaging. Of the patients who underwent concomitant pyelolithotomy, 18 (90%) were stone-free at last followup. All failures occurred within the first postoperative year. There were 12 complications in this series.

CONCLUSIONS:

In experienced hands laparoscopic pyeloplasty is an effective alternative treatment for symptomatic ureteropelvic junction obstruction. The results appear durable and comparable to open pyeloplasty with decreased postoperative morbidity.
