Abstract:
Objective To introduce the new technique of transperitoneal laparoscopic ureterovesical reimplantation and to evaluate its feasibility and clinical significance. Methods Overall,17 cases (5 men and 12 women) of ureterovesical obstruction (left,7 and right,10) were included.Of them,10 cases were diagnosed with simple congenital ureter outlet stricture;1 had calculi and polyp formation at right ureter outlet;2 had recurrent ureter outlet stricture after open ureterovesical reimplantation (1 of them had 2 calculi at lower part of the ureter);1 had double nephroureteral upper unit ureter outlet stricture with 2 calculi;2 had recurrent ureter outlet stricture after holmium laser section;1 with urinary TB had right ureter outlet stricture after left nephrectomy.Among the 17 cases,severe hydronephrosis occurred in 12,and moderate,in 5.Transperitoneal laparoscopic ureterovesical reimplantation was performed in the 17 cases (ureterovesical anastomosis in 15 and bladder flap ureterovesical reimplantation in 2). Results The operations were all successful in 17 cases with operating time of 90～160 min (mean, 112 min) and blood loss of 60～100 ml.The drainage tubes were removed 1～3 days after surgery without urine leakage.The urinary catheters were removed 1 week after surgery and double J stents,1 month after surgery. Six months after surgery cystography showed Ⅲ?urine reflux in 6 cases, Ⅰ?-Ⅱ? urine reflux in 5 and no reflux in 6.One year after surgery cystography showed Ⅲ? urine reflux in 3 cases, Ⅰ?～Ⅱ? urine reflux in 4 and no reflux in 10.During 3～24 months' follow-up, ultrasound B and IVU showed moderate hydronephrosis in 4 cases,mild,in 5 and no obvious hydronephrosis in 8. Conclusions Laparoscopic ureterovesical reimplantation is a feasible,less painful and minimally invasive alternative method for treatment of ureterovesical diseases.By comparison,bladder flap ureterovesical reimplantation has better anti-urine reflux effect but more complicated than ureterovesical anastomosis does.Long term efficacies of the methods need further observation.
