RESUMO
Objective To investigate the management and prevention of the complications of sigmoid rectal pouch for urinary division after radical cystectomy. Methods The clinical data of 34 patients who underwent a sigmoid rectal pouch procedure were analyzed retrospectively, and the clinical experience was summarized in the management and prevention of the complications of sigmoid rectal pouch for diversion. Results Twenty-six patients were followed up for 2 months to 11 years, and 10 patients lost in follow-up. The early follow-up results were as follows:3 patients had postoperative high fever with unilateral the kidney water, 1 patient had retropubic bleeding and need to stop bleeding, 3 patients suffered from wound split open and were performed relaxation suture, and 1 patient had sigmoid colon rectum bladder fistula 10d after operation. The late follow-up results were as follows:1 patient had urethral neoplasms recurrence, 5 patients developed distance metastases, and 5 patients developed nocturnal incontinence and worn safety pad. There were no hyperchloremic acidosis requiring clinical treatment, hydronephrosis as well as retrograde pelvis infection. Conclusions The operation of sigmoid rectal pouch for urinary division is fairly simple, with no serious complication. It is a better alternative diversion procedure, and should be accepted gradually by patients and surgeons.
RESUMO
Objective To assess the outcomes of modified spiral ileal orthotopic neobladder.Methods From January 1998 to January 2008, 32 patients (all male) underwent radical cystectomy and spiral ileal orthotopic substitution for muscle invasive bladder cancer. A segment of 40 to 45 cm ileal loop was isolated, detubularized, and reconfigured in spiral shape to form a pouch. Bilateral ureters were reimplanted by inserting the 1 cm distal segment into the pouch to form a Split-Cuff nipple.The bottom of the pouch was opened and anastomosed with the urethra (4 stitches). Results There were no perioperative deaths. The mean operative time was 281.2±48.7 min. Blood loss was 545.4±181.9 ml. Twenty cases required a blood transfusion, the mean volume of intraoprative blood transfusion was 430.8±235.9 ml. The average hospital stays were 26.8±9. 7 days. Rate of daytime continence was 93. 7% (30/32) while nighttime continence was 81.3% (26/32). Urodynamic studies were carried out in 23 cases 6 months after surgery. Neobladder capacity at first desire to urinate was 315.0± 33.4 ml(270-420 ml). The maximum neobladder capacity was 490. 3±39.7 ml(350-600 ml).The maximum flow rate (Qmax) was 16.5 ± 5.9 ml/s. Full resting pressure was 22. 5 ± 11.8 cm H2O. Peak voiding pressure was 78.3 ± 14.7 cm H2O. After mean 58. 4 months' follow up (range 22 to 132), 4 cases died of metastasis of bladder cancer. Conclusion Modified spiral ileal orthotopic neobladder is a reasonable option for treating invasive bladder cancer.
RESUMO
Objective To evaluate the outcomes of M-shaped orthotopic ileal neobladder. Methods A total of 42 male patients with malignant bladder tumors underwent M-shaped orthotopic ileal neobladder after extraperitoneal total cystoprostatectomy.A segment of 45 to 50cm ileal loop was isolated,detubularized,and reconfigured in “M”- shape to form a pouch.Bilateral ureters were reimplanted by means of inserting the 1 cm distal segment into the pouch.The bottom of pouch was opened and anastomosed with the urethra. Results The 42 patients were followed up for 12 to 96 months with a mean of 44 months.38 cases(90.5%) were well continent during daytime,and 36 cases(85.7%) were continent at night.The volume of the pouch was (361?48)ml at 12 months postoperatively. Urodynamic examination showed that the peak voiding pressure was (86.8?21.4)cm H 2O(1 cm H 2O=0.098 kPa).The maximum flow rate (Q max ) was(18.4?6.1)ml/s.No remarkable ureter reflux and obstruction were found.No patient was detected to develop recurrent urethral carcinoma. Conclusions Extraperitoneal cystectomy can prevent the abdomen from tumor contamination and protect the operative field from intestine interference.The ureter-inserting reimplantation technique is a simple anti-reflux anastomosis with lower rate of ureteral stenosis.Isolating the neobladder and ureters from the peritoneal cavity can reduce the postoperative complications of adhesive ileus,internal hernia,and urine leakage to peritoneal cavity.The neobladder is similar to original bladder in position,volume,shape,and anti-reflux of ureter connection.
