Outcomes of Laparoscopic Transperitoneal Pyeloplasty for the Treatment of Ureteropelvic Junction Obstruction in Adult Patients

Objective: Laparoscopic transperitoneal pyeloplasty (LTP) is being widely preferred in the treatment of ureteropelvic junction obstruction (UPJO). This study aims to assess the outcomes of treatment efficacy of LTP performed in our clinic for the treatment of UPJO in adult patients. Materials and Methods: Data of patients, who underwent LTP procedure in our clinic between 2004 and 2017, were reviewed retrospectively. Data of 116 patients in total were included in the study. The cases were reviewed in terms of demographic characteristics, complaints at admission, and clinical, laboratory and radiological findings. The patients were divided into two groups and correlation of demographic data (age, age group, and gender), side and presence of kidney stone with the presence of crossing vessel was investigated. Chi-square test, Student’s t-test and Fisher’s exact test were applied for statistical analysis. Results: The mean age of the patients was 29.9 (19-51) years. Eight patients were the secondary patients who underwent open surgery upon diagnosis of UPJO. Forty-one (35.3%) patients had the anomaly of crossing vessel compression, 17 (14.6%)-kidney stone, 5 (4.3%)-solitary kidney and 3 (2.5%) had horseshoe kidney. The mean operating time was 124 (80-245) minutes. No statistically significant correlation of the presence of crossing vessel with age, gender, side and presence of stone was found. The mean length of hospital stay was 3.05 (2-11) days and the mean postoperative follow-up time was 44 (12-120) months. Success rate was found to be 93.1%. One (0.8%) patient had perioperative and 10 (8.6%) patients had postoperative complications. Conclusion: LTP is a feasible, effective and reliable option in the treatment of UPJO with low complication rate and high success rate.
