Résumé
The most difficult, time-consuming, and critical steps of laparoscopic pyeloplasty (LPP) are ureteral spatulation, apical ureteral stitch placement, and ureteropelvic anastomosis. To simplify these critical steps, avoid the risk of ureteral shortening, and also minimize ureteral manipulation, we present a modified dismembered technique for suturing with the outcome of patients who underwent LPP using this technique. This study included 23 patients who were candidates for transperitoneal dismembered Anderson-Hynes LPP. The ureter was partially cut just below the ureteropelvic junction. The ureter was spatulated at its lateral aspect to cross the obstruction site and reach the normal ureter. The renal pelvis was obliquely cut equal to the size of ureteral spatulation. The ureter and pelvis were still connected partially. At this point, the first stitch was placed between the lower point of the spatulated ureter and the lowest corner of the renal pelvis. Anastomosis was performed by running sutures. No cases of internal organ injury and no cases of open surgery conversion were encountered. The radiologic success rate was 96%. After operation, in 1 patient, obstruction still existed and the patient underwent nephrectomy due to a nonfunctional obstructive kidney. This modification preserves total ureteral length and facilitates spatulation and suturing in transperitoneal laparoscopic dismembered pyeloplasty. The results showed that it is a useful method, especially for less-experienced surgeons.

BACKGROUND
The most difficult, time-consuming, and critical steps of laparoscopic pyeloplasty (LPP) are ureteral spatulation, apical ureteral stitch placement, and ureteropelvic anastomosis. To simplify these critical steps, avoid the risk of ureteral shortening, and also minimize ureteral manipulation, we present a modified dismembered technique for suturing with the outcome of patients who underwent LPP using this technique.
MATERIALS AND METHODS
METHODS
This study included 23 patients who were candidates for transperitoneal dismembered Anderson-Hynes LPP. The ureter was partially cut just below the ureteropelvic junction. The ureter was spatulated at its lateral aspect to cross the obstruction site and reach the normal ureter. The renal pelvis was obliquely cut equal to the size of ureteral spatulation. The ureter and pelvis were still connected partially. At this point, the first stitch was placed between the lower point of the spatulated ureter and the lowest corner of the renal pelvis. Anastomosis was performed by running sutures.
RESULTS
RESULTS
No cases of internal organ injury and no cases of open surgery conversion were encountered. The radiologic success rate was 96%. After operation, in 1 patient, obstruction still existed and the patient underwent nephrectomy due to a nonfunctional obstructive kidney.
CONCLUSIONS
CONCLUSIONS
This modification preserves total ureteral length and facilitates spatulation and suturing in transperitoneal laparoscopic dismembered pyeloplasty. The results showed that it is a useful method, especially for less-experienced surgeons.
