Laparoscopic Treatment for Secondary Ureteropelvic Junction Obstruction

Abstract

Background: Pelviureteric junction obstruction (PUJO) is one of the most frequent congenital anomalies of the urinary tract system. It is associated with pain, hydronephrosis, urinary tract infections, and eventually loss of renal function. Objective: To evaluate our institution in laparoscopic management of pelviureteric junction obstruction after failed open or laparoscopic surgery for pyeloplasty. Patients and methods: This study was conducted on 45 patients in two centers, Aswan Urology Department, and Sohage Urology Department. All of them have secondary pelviureteric junction obstruction. Results: This study included 24 females and 21 males, with the mean age of 30.2 ± 7.5 years (range 21 to 45 years), failed previous repair on the left side was in 29 cases while it was in 16 cases on the right side. Regarding BMI, it ranged from 21 to 30 with mean of 24.9 ± 3.1 kg/m2. The mean time after failure of primary pyeloplasty in both genders was 21.3 ± 8.2 months with a range of 10-38 months. The preoperative total renal function by DTPA was 80.7 ± 26.5. All cases were done laparoscopically without conversion to open surgery with a mean operative time of 154.9 ± 25.4 minutes (range from 80 to 185 minutes). The intra operative etiological finding of previous failure were peripelvic fibrosis and scarring in 34 cases, proximal ureteric stricture in 4, missed lower pole crossing vessels at initial surgery in 5 and a kink at the PUJ associated with redundant pelvis in two patients. Conclusion: Laparoscopic pyeloplasty is an effective minimal invasive alternative to open surgery in treatment of secondary pelviureteric junction obstruction.
