ABSTRACT
Objective:To evaluate the clinical value of Xing's ureteroileal anastomosis technique in radical cystectomy.Methods:The data of 38 patients who underwent radical cystectomy with Xing's ureteroileal anastomosis technique at Cancer Hospital, Chinese Academy of Medical Sciences and Beijing Chaoyang Hospital from July 2013 to June 2021 were retrospectively reviewed. There were 30 males and 8 females. The mean age was 61.6±15.1 years old. The mean body mass index (BMI) was 25.1±2.7 kg/m 2. The American Society of Anesthesiology (ASA) graded 25 cases as grade 1, 10 cases as grade 2 and 3 cases as grade 3. There were 35 cases with stage cT 2N 0M 0 and 3 cases with cT 3N 0M 0. All patients underwent radical cystectomy and ileal conduit, and the ureteroileal anastomosis was performed using the Xing's ureteroileal anastomosis technique. Afferent loop entry was divided equally into two lumens. After 1.5 cm-long lengthwise incisions, each ureter was directly and end-to-end anastomosed to the aforementioned lumens. Postoperative information was recorded, including ureteric stricture, ureteric reflux, hydronephrosis, anastomotic leakage, renal calculus, urinary tract infection, and pyelonephritis. Results:Ureteroileal anastomosis was performed successfully in 38 cases with 76 units. The median follow-up time was 35.6 (17.0, 46.3) months. Three patients developed unilateral anastomotic stenosis after operation. Five patients had unilateral ureteral reflux. Two patients had unilateral hydronephrosis. No anastomotic leakage, urinary tract infection, or pyelonephritis occurred after the operation. Renal calculus appeared in 3 cases, all on the left unit.Conclusions:Xing's ureteroileal anastomosis technique is a simple method with few postoperative and good functional outcomes.
ABSTRACT
Objective To compare split-cuff nipple and direct ureteroileal anastomosis during ureteroileal anastomosis.Methods Between December,2014 and March,2017,a prospective randomized study was conducted on 70 patients who underwent radical cystectomy and urinary diversion.In every patient,both ureters were randomized to be implanted using an antireflux,split-cuff nipple technique (group A) or a reflux,direct technique (group B).After pelvic lymph node dissection and radical cystectomy,a Mshape orthotopic ileal neobladder was constructed and two ureters were implanted with single-J tubes placed for 10-12 days.For split-cuff nipple technique,a 0.5 cm longitudinal incision in the ureter was made,and the ureteral wall was turned back on itself,construction a nipple.The cuff was stabilized at the corners with sutures.The ureter was then placed into the bowel with 0.5 cm nipple.The ureter was sutured to the full thickness of the bowel wall with interrupted 4-0 PDS.For direct technique,a 0.5 cm incision in the ureter was made,the full thickness of the ureter was sewn to the mucosa of the bowel.Results 70 patients were enrolled in the study,63 males and 7 females,(62.5 ± 10.4) years old.Over a median follow-up of 13.2 months,one patients had bilateral anastomosis stricture 3 months after operation,1 patient in group A had stricture 6 months after operation,2 patients in group B had stricture 6 and 12 months after operation,respectively.Six patients (8.6%) in group A found reflux compared with 21 patients (30.0%) in group B (P =0.004).The reflux pressure was (23.5 ± 9.0) cmH2O and (15.5 ± 4.9) cmH2O in group A and group B (P =0.042),respectively.The GFR of group A was (38.1 ± 7.6) ml/min compared with (38.6 ± 12.9) ml/min in group B at 12 months after operation.One patient in group A and four patients in group B had acute nephropyelitis.Four patients in group A had renal stones formation compared with 1 patients in group B.The time of anastomosis was (8.8 ± 3.5) minutes and (6.7 ± 1.5) minutes (P =0.037) for group A and group B,respectively.The patients in both groups had no urine leakage.Conclusion Compared with direct technique,split-cuff nipple technique had lower reflux rate,higher antireflux pressure and longer anastomosis time than direct technique.
