Background Bladder carcinoma is the most common malignant urological tumor in China. We present our preliminary experience and results of laparoscopic radical cystectomy (LRC) with orthotopic ileal neobladder in female patients with bladder carcinoma.
Methods From February 2003 to February 2008, 14 female patients with bladder carcinoma underwent LRC with orthotopic ileal neobladder. Nine of these patients underwent hysterectomy and ovariectomy, and the other 5 had preservation of the uterus and ovarian appendage. Standard bilateral pelvic lymphadenectomy was followed by radical cystectomy that was completed laparoscopically with hysterectomy and ovariectomy when needed. The tumor was removed by a 4-5 cm lower midline abdominal incision, followed by the construction of ileal neobladder and the extracorporeal anastomosis of ureter-neobladder. The neobladder was anastomosed to the urethral stump under a laparoscope.
Results The mean operative time and blood loss in the 14 patients were 350.2 minutes and 349.8 ml, respectively. Postoperative complications included uretero-pouch anastomotic stricture in 1 patient and pouch-vaginal fistula in 1 patient. Follow-up time of all patients ranged from 3 to 60 months, and 12 patients were followed up for more than 6 months and achieved micturition in half a year. One patient had occasional day-time urinary incontinence and 2 had night-time incontinence. Two patients who had undergone hystectomy and ovariectomy had voiding difficulties after one year, which was treated by intermittent self-catheterization. The mean volume of the neobladder and the residual urine were 333.6 ml and 31.2 ml, respectively. Surgical margins were tumor free for all patients. One patient had bone metastasis and died 11 months after the operation.
Conclusions LRC with orthotopic ileal neobladder in female patients is a technically feasible, safe and mini-invasive procedure with a low morbidity and acceptable neobladder function. Long-term follow-up is required to confirm the neobladder func  相似文献

Orthotopic ileal neobladder similar to original bladder   总被引:2,自引:2,他引:0  
Objective To report the surgical techniques and results of an 8-year follow-up study of 42 patients with a modified orthotopic ileal neobladder restoring normal anatomical relationship. Methods Total cystoprostatectomy was performed extraperitoneally. A 45-50 cm segment of the ileal loop was isolated, detubularized, and reconfigured into an “M”-shape to form a pouch. Bilateral ureters were implanted by inserting 1 cm distal segment into the pouch. The bottom of pouch was opened and anastomosed with the urethra. Results Forty-two patients were followed up for 6 to 96 months,90.5% of whom were continent in the daytime, and 85.7% at night. Two patients had a difficulty in urination. The average volume of the pouch was (361±48) ml at 12 months postoperation. Urodynamic examination showed the average peak voiding pressure was (86.8±21.4) cmH2O. The average maximum flow rate (Qmax) was (18.4±6.1) ml/s. No remarkable ureter reflux and obstruction were found. No patient was detected to have urethral carcinoma.Conclusions Extraperitoneal cystectomy can avoid the tumor contamination of the abdomen and intestinal interference of the operative field. The ureter-inserting implantation technique is a simple anti-reflux anastomosis method with less ureter stenosis rate. Isolating the neobladder and ureters from the peritoneal cavity can reduce the postoperative complications, such as adhesive ileus, internal hernia, and urine leakage into the peritoneal cavity. The neobladder is similar to the original bladder in position, volume, shape and anti-reflux ureter connection.  相似文献

Objective To investigate the effect of extramural support from the pouch and abdominal wall to enhance the continent mechanism of tapered ileum. Methods A total of 24 patients underwent a procedure in which an ileal segment was tapered into an efferent tube, of which a part was placed between the back surface of the rectus muscle and the ileal pouch wall. The internal orifice of the tapered ileum was anastomosed to the ileal pouch and its external orifice was anastomosed to the umbilicus. A urodynamic study of the efferent tubes and pouch was done 1.5 to 3 months and 6 to 24 months postoperatively. Results One patient died of heart disease 55 days postoperatively, while 22 of the remaining 23 were completely continent day and night. At 1.5 to 3 months, the urodynamic study of the efferent tubes demonstrated that the maximum closure pressure with a full pouch was 46-124 cmH20 (91.26±15.71 cmH20)and with an empty pouch was 34-84 cmH20 (67±10.60 cmH20). The difference in mean maximum closure pressure in the full and empty pouches was statistically significant (t=-11.78 and P=0.00001). At 6 to 24 months, a second urodynamic study was performed on 18 cases, demonstrating a reservoir capacity of 420 to 750 ml (481.67±78.83 ml). Reservoir pressure was 6 to 9 cmH(2)O (7.17±1.17 cmH20) when the pouch was filled to 50 ml, and 16 to 35 cmH(2)O (24.12±5.61 cmH20) when it was filled to maximum capacity. There was no contractive wave during the filling in any patient. Maximum closure pressure in the efferent tube was 80 to 194 cm H(2)O (98.89±26.34 cmH20) when the pouch was filled with saline, and 64 to 128 cmH(2)O (74.78±14.54 cmH20) when the pouch was empty. The difference in mean maximum closure pressure in the full and empty pouches was statistically significant (t=-7.58 and P=0.00003). Conclusions This study indicates that the continent mechanism of tapered ileum may be greatly enhanced by extramural support from the abdominal and pouch walls.  相似文献

Background We presented the technique and outcomes of laparoscopic radical cystectomy performed in 28 patients with bladder cancer to evaluate its clinical efficacy and feasibility. Methods Among the 28 patients, aged from 58 to 73 years (mean 68.5 years), 26 were transitional cell carcinoma grads Ⅱ-Ⅲ and 2 squamous carcinoma. Laparoscopic radical cystectomy plus bladder reconstruction was performed in all cases, among them 15 with ileum, 10 with rectum pouch, and 3 with ureterostomy. The operating time, the blood loss, the intestine function and the complications were observed. Results All procedures were successful. The operating times were 7--10 hours, the blood loss was 400--1500 ml (mean 850 ml), the intestine function recovered at 72 hours after operation, and all ureteral catheters were removed at 2 weeks after surgery. The results of intravenous urography were hormonal at 3-month, 1-year, and 2-year follow-up after surgery. Conclusions Laparoscopic radical cystectomy for invasive bladder cancer is safe and efficient, with good operating field, reliable hemostasis, mini-invasion, less celiac complications, and rapid recovery. This surgery is worth being extended.  相似文献

Objective To evaluate and compare 3 kinds of cecocloln urinary reservoir. Methods Perm pouch, indiana pouch or detenial cecocolon reservoir has been performed for 37 patients. The outcome was evaluated by urodynamic and clinically. Results Good continence has been achieved in all patients with an appendiceal continence mechanism. The capacity and intrareservoir pressure of detenial cecocolon was significantly different from penn or indiana pouch 3 months postoperatively (P<0.01) whereas the difference became in no significant 12 months postoperativelly (P>0. 05). The intrareservoir pressure on contraction was lower with penn pouch. Conclusion The penn or modified indiana pouch is better and more ideal as a urinary reservoir whereas the detenial cecocolon pouch is technically simpler. 6 refs,1 tab.  相似文献

A total of 92 patients with benign prostatic hyperplasia (BPH) were subjected to modified Madigan prostatectomy (MPC) for a much satisfactory effect in open prostatectomy surgery. Exposing anterior prostatic urethra near the bladder neck and conjunct cystotomy modified the MPC procedure. This modified procedure preserved prostatic urethra intact and could also deal with intracystic lesions at the same time. The intact of prostatic urethra was kept completely or largely in 86 cases. The amount of blood loss during modified procedure was less. The mean operative time was 105 min. Seventy patients had been followed up for 3-24 months. The postoperative average Qmax was 19.2ml/s. The cystourethrography revealed that the urethra and bladder neck were intact in 10 patients postoperatively. Furthermore, the prostatic urethra was obviously wider after modified MPC. The modified MPC can reduce the occurrence of urethra injury and enlarge the MPC indications. The modified technique is easy to perform with less complications and much satisfactory clinical result.  相似文献

Objective To investigate the clinical features and management of ureteral endometriosis. Methods Patients surgically and histologically diagnosed as ureteral endometriosis from January 2001 to January 2007 in Peking Union Medical College Hospital were retrospectively reviewed. Results Ten patients were diagnosed as ureteral endometriosis among 7 561 cases with surgically and histologically proved diagnosis of endometriosis, with an incidence of 0.132%. Nine out of 10 patients were extrinsic ureteral endometriosis and concomitant with severe pelvic endometriosis, and the other was intrinsic ureteral endometriosis. Hormone therapy failed in 2 patients with urinary tract obstruction. Ureterolysis was performed in 6 patients and ureterectomy was performed in 4 patients. One case of ureteral recurrence was observed in a postmenopausal woman without hormonal replacement therapy who received laparoscopic ureterolysis and hysterectomy with bilateral adnexectomy. No relapse was observed in the other 9 patients. Conclusions Ureteral endometriosis is a rare entity. The upper urinary tract should be evaluated in patients with severe endometriosis, even in postmenopausal women. The treatment of ureteral endometriosis usually requires surgery, while ureterolysis should not be performed in patients with extensive disease. As a form of adjuvant therapy of surgery, hormonal therapy is an appropriate option.  相似文献

Objective To evaluate the response to antiandrogen withdrawal in patients with advanced prostate cancer treated with combined androgen blockade.Methods Twenty-four cases of advanced prostate cancer (10in stage C and 14 in stage D) were retrospectively studied.All the patients were treated with combined androgen blockade(bilateral orchiectomy and flutamide).After initial response to hormone therapy for 7 to 36 months,flutamide was discontinued because of deterioration of the disease.Serum prostate specific antigen(PSA) levels were checked every 2 to 4 weeks and symptoms observed.Results The results following withdrawal of flutamide were as follows:8 patients showed a decling in PSA(mean 74.8%),of whom 6 cases had the PSA decling greater than 50%.Clinical symptoms improved in 4 cases.The nodules of the prostate were smaller than before in cases.The mean duration of response was 4.3 months.Conclusion In patients with hormone refractory advanced prostate cancer after initial combined androgen blockade therapy,a trial of “antiandrogen withdrawal”is a reasonable choice of therapeutic maneuver.  相似文献

Flow cytometry (FCM) was used to analyze the DNA content of epithelial cells in 26 cases of bladder cancer and 10 cases of nonneoplastic disease. Bladder tumor cells can be identified by aneuploidy or hyperdiploidy in histogram and/or a heterogeneity index (HI) greater than 2.30. The percentage of positive FCM in patients with bladder cancer was 84.62%. With respect to histological grading, it was 77.78% in grade 1, 90.91% in grade 2 and 100% in grade 3. While in nonneoplastic cases it was 10% Urinary exfoliative cytology was examined in all 26 patients with bladder cancer, with an accuracy of 61.54%. The DNA content of tumor cells increased with the increase of tumor grade and stage. Follow up showed that of 22 bladder cancer patients treated conservatively by transurethral resection or partial cystectomy, 8 recurred. The HI value in recurrent cases was higher than that in nonrecurrent cases. Among these 8 patients, 6 were correctly predicted by FCM. FCM appears to be an objective, sensitive and quantitative method for the diagnosis and monitoring of bladder cancer, and may be useful in estimating the prognosis of superficial bladder cancer.  相似文献

Background Urethroplasty of complex urethral stricture is a difficult procedure, and there is no widely accepted standard approach described in the published literature. We evaluated the efficacy and safety of urethroplasty using lingual mucosa grafts (LMGs) for the repair of urethral strictures. Methods Between August 2006 and April 2009, 92 cases of urethral strictures (length ranging from 2.5 cm to 18 cm, mean 6.5 cm) were treated using LMGs. Of the 92 patients, 38 with long-segment urethral strictures (9-18 cm) underwent dual LMG or LMG combined with foreskin flap or buccal mucosal graft urethroplasty. Results Follow-up was obtained for 3-33 months (mean 17.2 months) postoperatively. Complications occurred in 8 patients, including urinary fistulas in 4 patients; recurrent strictures developed in 4 patients at 3-4 months post-operatively. The remaining patients voided well postoperatively, with peak flows between 14.3 ml/s and 54.6 ml/s (mean 28.4 ml/s). Conclusions The tongue is an excellent source of graft material for the repair of anterior mucosal strictures. Dual LMG substitution urethroplasty can successfully treat longer, more complex urethral strictures.  相似文献
