Aim. To assess the perioperational parameters of laparoscopic pyeloplasty performed by the method of single incision laparoscopic surgery (SILS) in comparison with standard laparoscopy.

Patients and methods. 36 patients underwent pyeloplasty using SILS, 101 patients underwent standard pyeloplasty. Parameters evaluated: duration of the operation, blood loss, use of analgesic therapy, duration of hospitalization after surgery, complications, success rate of the operation.

Results. There were no statistically significant differences between the two groups (SILS and SL): by age, the side of hydronephrosis, sex, body mass index, the presence of the vessel as the cause of hydronephrosis, laparoscopic operations in the anamnesis. With the use of pyeloplasty performed by the SILS procedure, the time of surgery was significantly longer compared with standard pyeloplasty, which is probably related to technical difficulties caused by low ergonomics, especially in case of anastomosis, and in 19 cases an additional trocar was installed. At the same time, the severity of the pain in the first day after the operation is much less in the case of pyeloplastySILS. The remaining points of comparison showed no statistically significant difference.

Conclusion. Pyeloplasty by SILS method is a technically safe surgical intervention with the possibility of installing an additional trocar to overcome technical difficulties at any time during the operation. In addition, with pyeloplasty, SILS is much less painful in the early postoperative period. Single-port pyeloplasty can be used in expert clinics as an alternative to standard laparoscopic surgery in patients interested in cosmetic result.
