Objective:
To report clinical outcomes for laparoscopic pyeloplasty (LP) in children compared with open pyeloplasty (OP) and literature findings.
Patients And Methods:
In a prospective study, the outcomes of 57 consecutive transperitoneal LP in children from the age of 3 years were analyzed and compared with a matched historic control group of OP and with series of LP in the literature. Successful result was defined as resolution of symptoms, no conversion or re-operation, improved hydronephrosis, and/or improved renographic drainage.
Results:
Mean operative time was 177 (SD 50.5)min in the LP group and 108 (SD 25.6)min in the OP group (p < 0.001). Mean hospital stay was 1.2 (SD 0.46) days in the LP and 6.7 (SD 1.2) days in the OP group. Improvement in renographic drainage was observed more often after LP than after OP (98% vs 83%; p = 0.010). A successful result was reported in 56 (98%) LP and 54 (95%) OP (p = 0.298) patients. Our LP series demonstrates a high success rate compared to literature data.
Conclusions:
Our LP has a similar success rate and more often improved renographic drainage in comparison to OP. Furthermore, our LP demonstrates a shorter hospital stay and favorable outcomes compared to the literature. We thus regard LP as standard treatment for repair of ureteropelvic junction obstruction in children from the age of 3 years.
