Abstract
BACKGROUND Multiple primary cancers are rare occurrences that can involve either metachronous or synchronous development. It is particularly rare for an individual to have more than two primary cancers. In this report, we present a case study of an elderly man who was diagnosed with three heterochronous cancers in the renal pelvis, bladder, and colon. CASE SUMMARY On December 30, 2014, a 51-year-old Chinese man was admitted to our hospital with complaints of intermittent painless gross hematuria for the preceding week. A computed tomography (CT) scan revealed wall thickening in the left ureter's upper segment, while a CT urography revealed a left renal pelvis tumor. A successful laparoscopic radical resection of the left renal pelvis tumor was subsequently performed at Shanghai Zhongshan Hospital in January 2015. The pathological findings after the surgery revealed a low-grade papillary urothelial carcinoma of the renal pelvis. The final pathological tumor stage was pT1N0M0. After surgery, this patient received 6 cycles of intravenous chemotherapy with gemcitabine and carboplatin, as well as bladder infusion therapy with gemcitabine. On December 18, 2017, the patient was admitted once again to our hospital with a one-day history of painless gross hematuria. A CT scan showed the presence of a space-occupying lesion on the posterior wall of bladder. Cystoscopic examination revealed multiple tumors in the bladder and right cutaneous ureterostomy was performed under general anesthesia on December 29, 2017. The postoperative pathological findings disclosed multifocal papillary urothelial carcinoma of the bladder (maximum size 3.7 cm × 2.6 cm). The bladder cancer was considered a metastasis of the renal pelvis cancer after surgery. The pathological tumor stage was pT1N0M1. The patient refused chemotherapy after surgery. After another six years, the patient returned on February 28, 2023, complaining of periumbilical pain that had lasted six days. This time, a CT scan of the abdomen showed a tumor in the ascending colon, but a subsequent colonoscopy examination indicated a tumor in the descending colon. On March 12, 2023, a subtotal colectomy and an ileosigmoidal anastomosis were carried out under general anesthesia. Postoperative pathological findings revealed that all three tumors were adenocarcinomas. The final pathological tumor stage was pT3N0M0. The patient had an uneventful postoperative recovery and was discharged without complications. CONCLUSION The case of this elderly man presents a rare occurrence of metachronous primary cancers in the renal pelvis and colon. Bladder cancer is considered a metastasis of renal pelvis cancer after surgery. Optimal treatment can be implemented by evaluating the patient's histological features, clinical history, and tumor distribution correctly.

Abstract
INTRODUCTION The best approach of the bladder cuff (i.e., transvesical, extravesical, endoscopic) during radical nephroureterectomy (RNU) remains an unsolved question. The aim of this review is to compare the oncological and perioperative outcomes among three different approaches of the distal ureter during RNU. EVIDENCE ACQUISITION A literature search was conducted through June 2022 using PubMed/Medline, Embase, and Web of Science databases. Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed to identify eligible studies. The primary outcome was bladder recurrence-free survival and secondary outcomes included: perioperative outcomes, metastasis-free survival, and cancer-specific survival. EVIDENCE SYNTHESIS A total of 19 non-randomized studies comprising 6581 patients met our inclusion criteria. The risk of bladder recurrence, metastasis and cancer-related death did not differ significantly between each approach (all P>0.05). In subgroup analysis excluding patients with history of bladder cancer, the risk of bladder recurrence remained similar between each approach (all P>0.05). There was no significant difference in terms of operative time, estimated blood loss, length of hospital stay, and postoperative complications between each approach (all P>0.05). The main limitation is the retrospective design of 18/19 included studies. CONCLUSIONS The present systematic review and meta-analysis highlights the lack of high-level evidence on distal ureter management during RNU. On the basis of the available data, the present review supports the equivalence of different techniques of bladder cuff excision during RNU. The extravesical approach seems non-inferior to the transvesical approach in terms of oncological and perioperative outcomes.

Abstract
Purpose This study aimed to evaluate the effects of bladder cuff method on oncological outcomes in patients who underwent radical nephroureterectomy (RNU) for upper tract urothelial carcinoma. Materials and Methods The records of 1,095 patients treated with RNU performed at our hospital between 1994 and 2018 were retrospectively reviewed; 856 patients with no bladder tumor history were enrolled in the present study. The management of bladder cuff was divided into two categories: extravesical ligation (EL) or transvesical resection (TR). Survival was analyzed using the Kaplan-Meier method and Cox regression analyses were performed to determine which factors were associated with intravesical recurrence (IVR)–free survival (IVRFS), cancer-specific survival (CSS), and overall survival (OS). Results The mean patient age was 64.8 years and the median follow-up was 37.7 months. Among the 865 patients, 477 (55.7%) underwent the TR and 379 (44.3%) the EL. Significantly higher IVRFS (p=0.001) and OS (p=0.013) were observed in the TR group. In multivariable analysis, IVR, CSS, and OS were independently associated with the EL. Among 379 patients treated with the EL, eight underwent remnant ureterectomy. Based on radical cystectomy–free survival, significant difference was not observed between the two groups. However, significantly higher IVRFS was observed in the TR group when the tumor was located in the renal pelvis. Conclusion Intramural complete excision of the distal ureter during RNU should be the gold standard approach compared with EL for the management of distal ureter in terms of oncological outcomes.

Abstract
Upper tract urothelial carcinoma (UTUC) accounts for roughly 5% of urothelial carcinomas. Historically, the gold standard for high-risk or bulky low-risk UTUC was an open radical nephroureterectomy with formal bladder cuff excision (BCE). The development of novel endoscopic, laparoscopic, and robotic techniques has transformed this operation, yet no level I evidence exists at present that demonstrates the superiority of one strategy over another. While new approaches to nephroureterectomy in the last decade have shifted the management paradigm to decrease the morbidity of surgery, controversy continues to surround the approach to the distal ureter and bladder cuff. Debate continues within the urologic community over which surgical approach is best when managing UTUC and how various approaches impact clinical outcomes such as intravesical recurrence, recurrence-free survival (RFS) and disease-specific mortality (DSM). When focusing on the existing treatment algorithm, key metrics of quality include (I) removal of the entire specimen en bloc, (II) minimizing the risk of tumor and urine spillage, (III) R0 resection, and (IV) water-tight closure allowing for early use of prophylactic intravesical chemotherapy. In the absence of robust evidence demonstrating a single superior approach, the urologic surgeon should base decisions on technical comfort and each patient's particular clinical circumstance.

Abstract
Introduction: Management of the distal ureter during laparoscopic nephroureterectomy (LNU) for upper tract urothelial carcinoma (UTUC) is controversial. The aim of this review was to determine whether this affects oncological outcomes. Methods: A literature review was conducted searching MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials in June 2019. Studies reporting outcomes of LNU in UTUC using either open, laparoscopic, or endoscopic approaches to excise the distal ureter were identified. All eligible studies underwent critical appraisal and were excluded if not of sufficient quality. Cumulative analysis of the results was performed. Results: Nine studies with a total of 383 patients (168 open, 159 laparoscopic, and 56 endoscopic excision of distal ureter) were eligible for inclusion. Study design and outcome reporting were variable between studies. Mean age of patients was comparable (67.7 years versus 65.0 years versus 66.6 years). Mean follow-up duration was comparable between open and laparoscopic groups (46.2 months versus 45.5 months) but reduced in the endoscopic group (33.4 months). The open group had a higher proportion of high grade/G3 tumors and pT2-4 tumors when compared to the laparoscopic and endoscopic groups (P < .001 and P = .002). The open group had a higher rate of intravesical recurrence and the laparoscopic group had a higher rate of distant metastases (P < .001). Conclusion: This review has identified differences in oncological outcomes between different techniques of managing the distal ureter in LNU for UTUC. However, the poor reporting of potentially confounding factors does not enable any one technique to be recommended as superior and requires further research.

Assessing the impact of different distal ureter management techniques during radical nephroureterectomy for primary upper urinary tract urothelial carcinoma on oncological outcomes: A systematic review and meta-analysis. Int J Surg 2020; 75:165-173.

Abstract
OBJECTIVES To assess the oncological outcomes of several distal ureter management techniques in patients administered with radical nephroureterectomy (RNU) for primary upper urinary tract urothelial carcinoma (UTUC). METHODS A systematic search of PubMed, EMBASE, and the Cochrane Library was conducted to identify studies comparing outcomes following RNU under various surgical methods for bladder cuff management. Standard cumulative analyses of hazard ratios (HRs) with 95% confidence intervals (CIs) were performed using Review Manager (5.3). RESULTS Nine studies involving 4683 patients were selected based upon eligibility criteria. Meta-analysis of cancer-specific survival (CSS) and overall survival (OS) revealed no significant differences among intravesical incision of the bladder cuff (IVBC), extravesical incision of the bladder cuff (EVBC) and transurethral incision of the bladder cuff (TUBC) techniques. However, the IVBC technique appeared to have better recurrence-free survival (RFS) (HR = 1.37, p < 0.01) and intravesical recurrence-free survival (IRFS) (HR = 1.45, p < 0.01) compared with non-IVBC methods, including both TUBC and EVBC. When studies involving patients with bladder tumour history were excluded, the pooled statistic appeared to confirm that IVBC was associated with improved IRFS (HR = 1.25, p = 0.03) compared with EVBC and TUBC. No significant difference was found between the EVBC and TUBC groups (HR = 1.81, p = 0.32). CONCLUSIONS The findings suggest that IVBC is associated with improved oncologic outcomes and that it may be recommended for distal ureter management. However, caution must be taken because this recommendation is based upon a very limited number of clinical studies. Further research with enhanced outcome data collection and improved reporting is required to confirm these findings.

Abstract
Open radical nephroureterectomy (NU) with removal of the ureter and bladder cuff is the 'gold standard' in the treatment of high-grade urothelial cancers of the upper urinary tract. A salient issue is the management of the distal ureter and bladder cuff at time of surgery. Which technique confers superior oncologic benefit is of particular interest since this disease process is notoriously plagued with high intravesical recurrence rates. Although open radical NU is the 'gold standard', the maturation of minimally invasive surgery formidably challenges approaches considered 'gold standard'. We thus sought to critically review the literature comparing perioperative and oncologic outcomes in the approaches used to manage the distal ureter and bladder cuff in patients undergoing radical NU.

Abstract
INTRODUCTION AND OBJECTIVES Standard of care in upper tract urothelial cancer is nephroureterectomy with bladder cuff excision (BCE). However, alternative techniques such as transurethral incision/resection have been used to simplify distal ureterectomy. The optimum strategy is unclear, and current guidelines do not specify a gold standard technique. The objective of this study was to perform a systematic review of the literature, to compare BCE and transurethral distal ureter methods. MATERIALS AND METHODS A Cochrane and PRISMA-guided systematic literature search was conducted on English language articles from January 2000 to present, reporting on centers' experience with either BCE or transurethral distal ureterectomy. A cumulative meta-analysis comparison between the two procedures was performed. Primary outcome was intravesical recurrence. Secondary outcomes were local/distant recurrence, surgical margins, and disease-specific mortality (DSM). Groups were compared using chi-square analysis. RESULTS In total, 66 studies were included after excluding 1795. BCE and transurethral groups contained 6130 and 1183 patients, respectively. Mean/median age ranged from 57.5 to 75.2 years, and follow-up from 6.1 to 78 months. Level of evidence was low, with high risk of bias and small sample size (<100 patients) in 41 (62%) and 52 (79%) studies, respectively. Baseline cancer demographic analysis identified significantly higher rates of high grade, advanced stage, node-positive and carcinoma in situ disease in the BCE group. However, intravesical recurrence (23.6% vs 28.7%, p = 0.0002) and local/distant recurrence (17.9% vs 21.6%, p = 0.02) were significantly lower than the transurethral group. No difference was seen regarding surgical margins (3.1% vs 2.4%, p = 0.27) or DSM (16.8% vs 14.3%, p = 0.06). CONCLUSIONS No prospective, randomized comparisons exist for distal ureterectomy at nephroureterectomy. In this analysis, patients undergoing BCE had more advanced disease burden compared with the transurethral group. Despite this, the BCE group had statistically lower intravesical and local/distant recurrence. Further prospective research should be encouraged to identify gold standard ureter management.

Abstract
Upper tract urothelial carcinoma (UTUC) accounts for approximately 5% of all urothelial carcinoma. There are many risk factors for UTUC, including environmental and genetic risk factors, some of which are in common with bladder cancer. The gold standard surgical management of UTUC is radical nephroureterectomy (RNU) with excision of bladder cuff, which is increasingly being performed laparoscopically or robotically with various methods used for the distal ureter. There are increasing numbers of patients being treated endoscopically, with excellent oncological outcomes in low-grade disease. The use of topical BCG and chemotherapy agents has been extrapolated from bladder cancer and may be an adjunct to endoscopic management in those patients in whom it is imperative to avoid RNU.

Abstract
BACKGROUND There is a lack of consensus regarding the optimal approach to the bladder cuff during radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). OBJECTIVES To compare the oncologic outcomes following RNU using three different methods of bladder cuff management. DESIGN, SETTING, AND PARTICIPANTS Retrospective analysis of 2681 patients treated with RNU for UTUC at 24 international institutions from 1987 to 2007. INTERVENTION Three methods of bladder cuff excision were performed: transvesical, extravesical, and endoscopic. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Univariable and multivariable models tested the effect of distal ureter management on intravesical recurrence, recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS). RESULTS AND LIMITATIONS Of the 2681 patients, 1811 (67.5%) underwent the transvesical approach; 785 (29.3%), the extravesical approach; and 85 (3.2%), the endoscopic approach. There was no difference in terms of RFS, CSS, and OS among the three distal ureteral management approaches. Patients who underwent the endoscopic approach were at significantly higher risk of intravesical recurrence compared with those who underwent the transvesical (p=0.02) or extravesical approaches (p=0.02); the latter two groups did not differ from each other (p=0.40). Actuarial intravesical RFS estimates at 2 and 5 yr after RNU were 69% and 58%, 69% and 51%, and 61% and 42% for the transvesical, extravesical, and endoscopic approaches, respectively. In multivariate analyses, distal ureteral management (p=0.01), surgical technique (open vs laparoscopic; p=0.02), previous bladder cancer (p<0.001), higher tumor stage (trend; p=0.01), concomitant carcinoma in situ (CIS) (p<0.001), and lymph node involvement (trend; p<0.001) were all associated with intravesical recurrence. Excluding patients with history of previous bladder cancer, all variables remained independent predictors of intravesical recurrence. CONCLUSIONS The endoscopic approach was associated with higher intravesical recurrence rates. Interestingly, concomitant CIS in the upper tract is a strong predictor of intravesical recurrence after RNU. The association of laparoscopic RNU with intravesical recurrence needs to be further investigated.

Abstract
CONTEXT The European Association of Urology (EAU) Guideline Group for urothelial cell carcinoma of the upper urinary tract (UUT-UCC) has prepared new guidelines to aid clinicians in assessing the current evidence-based management of UUT-UCC and to incorporate present recommendations into daily clinical practice. OBJECTIVE This paper provides a brief overview of the EAU guidelines on UUT-UCC as an aid to clinicians in their daily practice. EVIDENCE ACQUISITION The recommendations provided in the current guidelines are based on a thorough review of available UUT-UCC guidelines and papers identified using a systematic search of Medline. Data on urothelial malignancies and UUT-UCCs in the literature were searched using Medline with the following keywords: urinary tract cancer, urothelial carcinomas, upper urinary tract, carcinoma, transitional cell, renal pelvis, ureter, bladder cancer, chemotherapy, nephroureterectomy, adjuvant treatment, neoadjuvant treatment, recurrence, risk factors, and survival. A panel of experts weighted the references. EVIDENCE SYNTHESIS There is a lack of data in the current literature to provide strong recommendations due to the rarity of the disease. A number of recent multicentre studies are now available, whereas earlier publications were based only on limited populations. However, most of these studies have been retrospective analyses. The TNM classification 2009 is recommended. Recommendations are given for diagnosis as well as for radical and conservative treatment; prognostic factors are also discussed. Recommendations are provided for patient follow-up after different therapeutic options. CONCLUSIONS These guidelines contain information for the diagnosis and treatment of individual patients according to a current standardised approach. When determining the optimal treatment regimen, physicians must take into account each individual patient's specific clinical characteristics with regard to renal function including medical comorbidities; tumour location, grade and stage; and molecular marker status.

Abstract
We present the results of a pure retroperitoneoscopic/ extraperitoneal nephroureterectomy (RENU) for upper urinary tract transitional cell cancer (UT-TCC). After establishment of RENU in benign indications (n=21 Patients), 14 patients (age range 51-92 years, mean 71.6) with UT-TCC have undergone the technique in our clinic from October 2005 to October 2008. This paper reports the operative procedure, clinical results and follow up. Total operative time was 110-240 minutes (median 154.5). Average blood loss was 132 mL. Tumor localization in oncology patients was renal pelvis (63.6%), ureter (18.2%) or both (18.2%). Postoperative tumor stages were Ta (n=2), Tis (n=2), T1 (n=3), T2 (n=3) and T3 (n=4) without lymph node involvement. No perioperative complications were observed. Urethral catheters were removed on Day 6-8 post surgery (median Day 7). Recovery to normal life activity ranged from 8 to 30 days (mean 17.8). During the 4-36 month (median 23) follow-up period, there was one mortality due to cancer progression. Four patients had developed superficial bladder cancer disease requiring regular cystoscopic resections. One patient had coincidental Bellini duct renal tumor and developed psoas metastasis after eight months. The 2-year tumor specific survival rate is 91%. The retroperitoneoscopic/ extraperitoneal nephroureterectomy is a lowrisk and minimally invasive procedure to be used whenever nephroureterectomy is indicated. It is an attractive alternative to both laparoscopic and open techniques and adheres to the oncological principles of radical nephroureterectomy. Short-term follow-up data showed no increased risk of tumor recurrence. However, long-term results are needed before this technique can be established as standard UT-TCC therapy.

Abstract
Study Type - Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? The resection of the distal ureter and its orifice is an oncological principle during radical nephroureterectomy which is based on the fact that it represents a part of the urinary tract exposed to a considerable risk of recurrence. After removal of the proximal part it is hardly possible to image or approach it by endoscopy during follow-up. Recent publications on survival after nephroureterectomy do not allow the conclusion that removal of distal ureter and bladder cuff are useless. Several techniques of distal ureter removal have been described but they are not equivalent in term of oncological safety. • The standard treatment of upper urinary tract urothelial carcinomas (UUT-UCs) must obey oncological principles, which consist of a complete en bloc resection of the kidney and the ureter, as well as excision of a bladder cuff to avoid tumour seeding. • The open technique is the 'gold standard' of treatment to which all other techniques developed are necessarily compared, and various surgical procedures have been described. • The laparoscopic stapling technique maintains a closed system but risks leaving behind the ureteric and bladder cuff segments. • Transvesical laparoscopic detachment and ligation is a valid approach from an oncological stance but is technically difficult. The major inconvenience of the transurethral resection of the ureteric orifice and intussusception techniques is the potential for tumour seeding. • Management of the distal ureter via the robot-assisted laparoscopic method is technically feasible, but outcomes from these procedures are still preliminary. • Therefore, prospective comparative studies with more thorough explorations of these techniques are needed to solve the dilemma of the management of the distal ureter during nephroureterectomy. However, bladder cuff excision should remain the standard of care irrespective of the stage of the disease.

Abstract
OBJECTIVES To determine the surgical and oncologic outcomes in patients who underwent retroperitoneoscopic nephroureterectomy (RNU) in comparison to standard open nephroureterectomy (ONU) for upper urinary tract transitional cell carcinoma (TCC). PATIENTS AND METHODS From April 2001 to January 2007, 60 total nephroureterectomy were performed for upper tract TCC at Siriraj Hospital. Of the 60 patients, thirty-one were treated with RNU and open bladder cuff excision, and twenty-nine with ONU. Our data were reviewed and analyzed retrospectively. The recorded data included sex, age, history of bladder cancer, type of surgery, tumor characteristics, postoperative course, disease recurrence and progression. RESULTS The mean operative time was longer in the RNU group than in the ONU group (258.8 versus 190.6 min; p = 0. < 001). On the other hand, the mean blood loss and the dose of parenteral analgesia (morphine sulphate) were lower in the RNU group (289.3 versus 313.7 ml and 2.05 versus 6.72 mg; p = 0.868 and p = 0.018, respectively). There were two complications in each group. No significant difference in p stage and grade in both-groups (p = 0.951, p = 0.077). One patient with RNU had lymph node involvement, three in ONU. Mean follow up was 26.4 months (range 3-72) for RNU and 27.9 months (range 3-63) for ONU. No port metastasis occurred during follow up in RNU group. Tumor recurrence developed in 11 patients (bladder recurrence in 9 patients, local recurrence in 2 patients) in the RNU group and 14 patients (bladder recurrence in 13 patients, local recurrence in 1 patient) in the ONU group. No significant difference was detected in the tumor recurrence rate between the two procedures (p = 0.2716). Distant metastases developed in 3 patients (9.7%) after RNU and 2 patients (6.9%) after ONU. The 2 year disease specific survival rate after RNU and ONU was 86.3% and 92.5%, respectively (p = 0.8227). CONCLUSION Retroperitoneoscopic nephroureterectomy is less invasive than open surgery and is an oncological feasible operation. Thus, the results of our study supported the continued development of laparoscopic technique in the management of upper tract TCC.

Abstract
OBJECTIVE To compare evolution in patients with urothelial upper tract tumor (UUTT) in whom we performed the classic open approach to the distal ureter with those in whom whe performed the endoscopic approach. We study the bladder recurrences in each group and the factors which may influx on the evolution. MATERIAL AND METHODS Retrospective review of nephroureterectomies in our department in the last 20 years. Group A (n:24): double incision (lumbar and pelvic incision), Group B (n:29): endoscopical approach of the distal ureter and classic lumbar incision. A descriptive study is first performed in which we review: sex, and patients age, background transuretral resection of bladder tumor (TURBT), UUTT side, and UUTT location (calices, pelvis or urether). Pathological stage and tumor grade are also exposed. Secondly, a review of the bladder recurrences in each group is performed. In order to find differences between de groups we used the Fisher's Exact test. RESULTS We observed that in terms of bladder recurrence there is a statistically significant difference between the two groups favoring Group B (p < 0.036), which means that there are less bladder recidives when perform endoscopic approach of distal ureter. Noneless due to the groups inhomogeneity in tumor stage, grade, and location, this differences seem to be associated to these sigues, more than to the approach to the ureter as an independant variable. In that concerning to the eventual relationship between bladder recidive and background of previous TURBT, we have not found any differences between the two groups but there are statystically significant difference in the global series. The small number of recurrences (13) does not allow us to establish a well based conclusion on this issue, but it seems that the background of previous TURBT is an important factor that may influx in posterior bladder recurrences. CONCLUSIONS In our results, endoscopic approach of distal ureter in nephroureterectomy for UUTT does seems to positively influx in the posterior chance of bladder recurrences. But the studied sample is small and the two groups have not been aleatorized because of ethical reasons. May the low number of cases affect the test's statistical potency. It seems that previous TURBT may conditionate these recurrences, as we show in global serie. It should be necessary a prospective and statistically analised multicenter trial to understand if distal ureter approach influx on the evolution of these tumors.

Abstract
OBJECTIVE The aim of this study was to clarify whether intravesical recurrence of upper urinary tract cancer after treatment is related to the mode of surgery or other oncological factors. METHODS We evaluated 106 patients (mean age 70.4 years; mean follow-up 24.0 months) who underwent surgery for the upper urinary tract cancer at Hiroshima University and its affiliated hospitals between January 1995 and August 2005. Seventy-nine of the patients underwent retroperitoneoscopy-assisted radical nephroureterectomy (RN) and 27 underwent nephroureterectomy by open surgery (OS). Fifty-two patients had renal pelvic tumors, 48 had ureteral tumors, and six had both renal pelvic and ureteral tumors. Twenty-eight (26%) of the 106 patients had a pre-operative history of bladder cancer. We identified the risk factors predicting intravesical recurrence of upper urinary tract cancer according to the type of previous surgery using the Kaplan-Meier method, log-rank test, and univariate and multivariate analysis using the Cox proportional hazards model. RESULTS Thirty-one (29%) of the 106 patients developed bladder tumors post-operatively. The 2-year intravesical recurrence-free rate was 55% in the RN group and 60% in the OS group. There was no significant difference (P = 0.51, log-rank test) in the rate of intravesical recurrence between the two groups. Multivariate analysis identified only a history of pre-operative bladder tumor (HR = 3.25, P = 0.003) as a predictor of post-operative intravesical recurrence. CONCLUSIONS Intravesical recurrence after surgery for upper urinary tract cancer is not related to the mode of surgery (i.e. laparoscopy-assisted or open surgery) employed. The only risk factor for intravesical recurrence is a history of bladder cancer.

Abstract
OBJECTIVES To determine the oncologic safety of laparoscopic nephroureterectomy (LNU), we compared the long-term oncologic outcome of LNU versus open nephroureterectomy (ONU) in patients with upper tract transitional cell carcinoma. METHODS A total of 367 nephroureterectomy procedures were performed at our institutes for upper tract transitional cell carcinoma without distant metastases. Of 224 patients without concomitant or previous bladder cancer, 58 underwent LNU with open intact specimen retrieval plus open distal ureter and bladder cuff removal and 166 underwent ONU. Their data were reviewed and analyzed retrospectively. The mean follow-up was 13.6 months (range 14 to 34) for the LNU group and 28.0 months (range 14 to 36) for the ONU group. RESULTS Bladder recurrence was recognized in 19 patients (32.8%) after LNU at a median follow-up of 5.6 months compared with 63 patients (38.0%) after ONU. Local recurrence only developed in 2 patients (1.1%) after ONU. One port site metastasis occurred in a patient who had undergone LNU. Distant metastases developed in 10 patients (17.2 %) after LNU and 33 patients (19.9%) after ONU. The frequency of bladder recurrence, local recurrence, and distant metastases did not differ significantly between the two groups. The actual disease-free 2-year survival rates were similar (75.6% versus 81.7%). In all patients, the risk of metastases and death increased with advanced tumor stage and grade, but not by surgical procedure. CONCLUSIONS In the surgical management of upper tract transitional cell carcinoma, LNU does not negatively affect long-term oncologic control and can be considered an alternative modality. Tumor stage and grade are, however, important prognostic factors in the incidence of metastases and cancer-specific mortality.

Abstract
As with the increasingly common presence of laparoscopic surgery in renal adenocarcinoma, the same situation is also occurring with radical management of tumours of the upper urothelium. In this type of clinical condition, it is important to emphasize the different ways to mobilise the distal ureter (with transuretral resection or unroofing, pure laparoscopy, or open), and to take into account that this tumour has the highest risk of implantation at the ports of entry. Here, we conduct a literature review and up-date of the different approaches to the distal urethra.

Abstract
OBJECTIVES We retrospectively compared two techniques of transurethral management of the lower ureter in nephroureterectomy. PATIENTS AND METHODS From August 1992 to December 2003, 34 patients underwent either transurethral detachment of the intramural ureter and cephalad extraction ("pluck"; Group 1, N = 18) or transection of the ureter with subsequent transurethral extraction (Group 2, N = 16). Choice of technique was left to the operating surgeon. All patients with upper tract urothelial carcinoma (TCC) were regularly followed by cystoscopy and abdominal ultrasound. RESULTS Of the 34 patients, 29 had upper tract TCC. Mean follow-up in these was 44 months (range: 1-129), with 24 (83.8%) over 24 months. On follow-up, 14 bladder tumors (all superficial) occurred in 7 patients (24.1%), but in no case on the scar of the excised ureteral orifice. No extravesical recurrences in the former ureteral bed were found. Of the 29 with upper tract TCC, 19 (65.5%) are alive without disease (median 45 months, range: 6-129), 5 (17.2%) have died with no evidence of disease (median 34 months, range: 20-58), and 4 (13.8%) have died from progressive disease (median 18 months, range: 1-33); 1 patient was lost to follow-up at 34 months with no evidence of disease. Differences between techniques with regard to blood loss, operative time, complications, and oncologic outcome were not significant. CONCLUSION Both techniques proved technically and oncologically safe. Bladder tumor recurrence rate was in the range reported for classic nephroureterectomy. No extravesical tumor recurrence in the former ureteral bed or on the scar of the resected ureteral orifice occurred.
