PURPOSE: Hand-assisted laparoscopic surgery (HALS) is a minimally invasive surgical technique with the combined benefits of laparoscopic surgery while allowing the use of the surgeon's hand for better tactile control. Obesity has been associated with higher conversion rates with multiport laparoscopic surgery, but not with HALS. This study aimed to examine the versatility of HALS in various clinical contexts. METHODS: All HALSs performed at 2 major tertiary centers in Sydney were prospectively collected for retrospective analysis. Variables including age, sex, body mass index (BMI), previous surgeries, pathologies including size and T-stage, and the number of conversions to a midline laparotomy were examined. RESULTS: A total of 121 HALS colorectal resections were analyzed. The median age of the patients was 62 years, with 63.6% being women. Seven patients required conversion to a midline laparotomy. Of the 121 patients, 50.2% were overweight or obese, and 52.9% had undergone previous abdominal/pelvic operations. However, neither obesity nor abdominal adhesions from previous operations were an indication for conversion to an open laparotomy in any of the 7 converted patients. The presence of intra-abdominal adhesions did not impact the operative time. HALS allowed access to the entire colon and rectum and allowed resection of the bladder, uterus, and ureter, when these organs were involved. CONCLUSION: HALS is a versatile, minimally invasive technique, which is independent of the patient's BMI, for performing a colorectal resection.

PURPOSE: To investigate oncological outcomes based on bladder cuff excision (BCE) during radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC) and to provide clinical evidence of tumor recurrence in patients without BCE. MATERIALS AND METHODS: We retrospectively collected data of 372 consecutive patients who underwent RNU at our institution from May 1989 through October 2010. After excluding some data, we reviewed 336 patients for the analysis. RESULTS: Of the patients who underwent RNU with BCE (n=279, 83.0%) and without BCE (n=57, 17.0%), patients without BCE had poorer cancer-specific and overall survival rates. Among 57 patients without BCE, 35 (61.4%) experienced tumor recurrence. Recurrence at the remnant ureter resulted in poor oncological outcomes compared to those in patients with bladder recurrence, but better outcomes were observed compared to recurrence at other sites. No significant predictors for tumor recurrence at the remnant ureter were identified. In patients without BCE, pathological T stage [hazard ratio (HR), 5.73] and lymphovascular invasion (HR, 3.65) were independent predictors of cancer-specific survival, whereas age (HR, 1.04), pathological T stage (HR, 5.11), and positive tumor margin (HR, 6.50) were independent predictors of overall survival. CONCLUSION: Patients without BCE had poorer overall and cancer-specific survival after RNU than those with BCE. Most of these patients experienced tumor recurrence at the remnant ureter and other sites. Patients with non-organ confined UTUC after RNU without BCE may be considered for adjuvant chemotherapy with careful follow-up.

The prognostic impact of body mass index (BMI) in patients with upper tract urothelial carcinoma (UTUC) is an ongoing debate. Our study aimed to investigate the prognostic role of BMI in patients treated with radical nephroureterectomy (RNU) for UTUC from a multi-institutional Korean collaboration. We retrospectively reviewed data from 440 patients who underwent RNU for UTUC at four institutions in Korea. To avoid biasing the survival estimates, patients who had previous or concomitant muscle-invasive bladder tumors were excluded. BMI was categorized into approximate quartiles with the lowest quartile assigned to the reference group. Kaplan-Meier and multivariate Cox regression analyses were performed to assess the influence of BMI on survival. The lower quartile BMI group showed significantly increased overall mortality (OM) and cancer specific mortality (CSM) compared to the 25%-50% quartiles and upper quartile BMI groups. Kaplan-Meier estimates showed similar results. Based on multivariate Cox regression analysis, preoperative BMI as a continuous variable was an independent predictor for OM and CSM. In conclusion, preoperative underweight patients with UTUC in Korea survive less after RNU. Preoperative BMI may provide additional prognostic information to establish risk factors.

PURPOSE: Urinary calculi is a familiar disease. A well-known complication of endourological treatment for impacted ureteral stones is the formation of ureteral strictures, which has been reported to occur in 14.2% to 24% of cases. MATERIALS AND METHODS: This was a prospective study. Ureterotripsy treatment was used on patients with impacted ureteral stones. Then, after 3 months and 6 months, the condition of these patients was assessed by means of a kidney-ureter-bladder (KUB) ultrasound. If the KUB ultrasound indicated moderate to serious hydronephrosis, the patient was further assessed by means of a computed tomography intravenous urogram or retrograde pyelogram to confirm the occurrence of ureteral strictures. RESULTS: Of the 77 patients who participated in the study, 5 developed ureteral strictures. Thus, the stricture rate was 7.8%. An analysis of the intraoperative risk factors including perforation of the ureter, damage to the mucous membrane, and residual stone impacted within the ureter mucosa revealed that none of these factors contributed significantly to the formation of the ureteric strictures. The stone-related risk factors that were taken into consideration were stone size, stone impaction site, and duration of impaction. These stone factors also did not contribute significantly to the formation of the ureteral strictures. CONCLUSIONS: This prospective study failed to identify any predictable factors for ureteral stricture formation. It is proposed that all patients undergo a simple postoperative KUB ultrasound screening 3 months after undergoing endoscopic treatment for impacted ureteral stones.

PURPOSE: To evaluate the impact of adjuvant chemotherapy (AC) in patients with upper tract urothelial carcinoma and lymphovascular invasion (LVI) after radical nephroureterectomy (RNU). MATERIALS AND METHODS: We retrospectively analyzed the clinical records and clinicopatholgic outcomes of patients (n=552) treated with RNU between 1986 and 2013. Patients treated with neoadjuvant chemotherapy and those for whom LVI status was not recorded were excluded. Patients were divided into two groups according to LVI (n=86) or no LVI (n=256). RESULTS: The study included 344 patients (240 men and 104 women) with a median of 53.9 months of follow-up (range, 1-297 months) after RNU. Tumors were organ confined (T2/N0) in 211 (61.3%) and tumor grade high in 291 (84.6%). AC was administered in 64 patients (18.6%). A total of 280 patients (81.4%) were treated with surgery alone. Patients with LVI tended to be older (p=0.049), have a higher pT stage (pT3/T4, p<0.001), be pN+ (p<0.001), have a high tumor grade (p<0.001), and experience recurrence (p<0.001). In the multivariate analysis, LVI was an independent prognostic factor for cancer-specific survival and overall survival (p=0.002 and p<0.001, respectively). The multivariate analysis demonstrated that in the subgroup of patients with LVI, AC was a significant prognostic factor for cancer-specific survival and overall survival (hazard ratio, 0.51; p=0.027 and hazard ratio, 0.50; p=0.025, respectively). CONCLUSIONS: AC does not seem to reduce mortality in patients with advanced upper tract urothelial carcinoma after RNU. In the subgroup of patients with LVI, AC had a positive impact on cancer-specific survival and overall survival. LVI would be helpful for selecting patients who are appropriate for AC.

PURPOSE: Systemic inflammatory responses, which are defined in terms of the Glasgow prognostic score (GPS), have been reported to be independent predictors of unfavorable outcomes in various human cancers. We assessed the utility of the GPS as a predictor of intravesical recurrence after radical nephroureterectomy (RNU) in upper urinary tract carcinoma (UTUC). MATERIALS AND METHODS: We collected data for 147 UTUC patients with no previous history of bladder cancer who underwent RNU from 2004 to 2012. Associations between perioperative clinicopathological variables and intravesical recurrence were analyzed by using univariate and multivariate Cox regression models. RESULTS: Overall, 71 of 147 patients (48%) developed intravesical recurrence, including 21 patients (30%) diagnosed with synchronous bladder tumor. In the univariate analysis, performance status, diabetes mellitus (DM), serum albumin, C-reactive protein, GPS, and synchronous bladder tumor were associated with intravesical recurrence. In the multivariate analysis, performance status (hazard ratio [HR], 2.33; 95% confidence interval [CI], 1.41-3.85; p=0.001), DM (HR, 2.04; 95% CI, 1.21-3.41; p=0.007), cortical thinning (HR, 2.01; 95% CI, 1.08-3.71; p=0.026), and GPS (score of 1: HR, 6.86; 95% CI, 3.69-12.7; p=0.001; score of 2: HR, 5.96; 95% CI, 3.10-11.4; p=0.001) were independent predictors of intravesical recurrence. CONCLUSIONS: Our results suggest that the GPS as well as performance status, DM, and cortical thinning are associated with intravesical recurrence after RNU. Thus, more careful follow-up, coupled with postoperative intravesical therapy to avoid bladder recurrence, should be considered in these patients.

OBJECTIVE:
To study the effect and outcome of Boari bladder flap plasty surgery for the treatment of kidney-sparing strategy for patients with middle and lower ureteral carcinoma.
METHODS:
Database at the department of urology in the Second Xiangya Hospital from 2002-2007 was screened and all cases of primary solitary lower ureteral carcinoma treated with Boari bladder flap plasty surgery or radical nephroureterectomy were collected. We performed a retrospective review of the clinical data including sex, age, smoking history, tumor site, size, stage, grade, bladder recurrence, renal function et al and evaluated survival rate. The Cox proportional hazards regression model was build to analyze the correlation between each variable and survival time.
RESULTS:
Thirty nine patients in total were enrolled, including 16 cases underwent Boari bladder flap plasty surgery and 23 cases underwent radical nephroureterectomy. The median follow-up time was 53 months (range 10-84 months). During the follow-up time, 18 patients died, including 6 patients treated with Boari bladder flap plasty surgery and 12 patients treated with radical nephroureterectomy. The estimated bladder recurrence-free survival rate and cancer-specific survival rate at 5 years were 63% vs 59% and 73.8% vs 73.5%, respectively (P>0.05). The survival rate at 5 years and the overall survival rate were 61% vs 57 % and 64.8% vs 58.1% respectively in the 2 groups (P>0.05). There was no significant difference in renal function before surgery between the two groups [creatinine clearance 57 (32-104 ) mL/ min vs 55 (30-102) mL/ min, P>0.05]. Patients underwent Boari bladder flap plasty showed better renal function than patients underwent radical nephroureterectomy [creatinine clearance 55 (35-102) mL/ min vs 43 (30-89) mL/min, P<0.05]. In multivariate Cox regression analysis, the tumor size, pT stage, tumor cell grade and the estimated glomerular filtration rate level were independent factors that affected the overall survival rate of the patients (P<0.05). The tumor size, pT stage and tumor cell grade were positively correlated to the survival time, and the estimated glomerular filtration rate was negatively correlated to the survival time.
CONCLUSION
Boari bladder flap plasty surgery could be used to treat lower ureteral carcinoma. Compared with radical nephroureterectomy, Boari bladder flap plasty surgery has equal survival rate and shows superior postoperative renal function.

Ureteral fibroepithelial polyp accompanied by intussusception is a rare occurrence. Currently, most ureteral polyps could be removed readily by ureteroscopy. Nevertheless, endoscopic resection can be difficult in patient with a large polyp, especially accompanied by an intussusception. We described our experience and laparoscopic technique for treatment of a symptomatic 63-year-old woman who presented with a pedunculated, 9-cm-long, left lower ureteral, fibroepithelial polyp accompanied by a 2-cm-long intussusception.
