PlumX metrics:
The process of improving one’s skills over time is called a “learning curve”. This term has attracted great attention during the last decades, especially in relation to laparoscopic techniques.

To assess the outcome of paediatric laparoscopic pyeloplasty (LP).

Material and methods
Retrospective analysis of the consecutive LPs. The inclusion criteria: (1) children aged < 18 years, (2) transperitoneal approach, and (3) the same operating paediatric urologist (RC). Patients with a history of any procedure on the upper urinary tract were excluded. Any surgical reintervention during follow-up was defined as a failure. The outcomes of LPs performed before 2012 (G1) were compared to those conducted between 2012 and 2016 (G2). Fisher’s exact test was used for statistical analysis.

Ninety patients met the inclusion criteria, and a total of 95 LPs were performed. The mean operation time was 155 min, and the mean hospitalisation period was 2.4 days. In G1, 19 patients underwent Anderson-Hynes LP, 16 had Fenger non-dismembered LP and two underwent vascular hitch. In G2, 54, 2 and 2 patients underwent these procedures, respectively. The overall success rate was 91.5%. There were six failures in G1 and three in G2 (p = 0.147). Of the Anderson-Hynes LPs, 1/19 in G1 and 3/58 in G2 required reintervention (p = 1). For Fenger LPs, this was 4/16 and 0/2, respectively (p = 1). Only one patient required reoperation after vascular hitch.

The surgeons’ learning curve reflects their experience with regard to the entire therapeutic process, but not exclusively their manual skills.
