Abstract
INTRODUCTION Nephroureterectomy with excision of a cuff of bladder remains the standard for managing upper tract transitional cell carcinoma (TCC). Increasing use of diagnostic upper tract endoscopy has underlined the importance of obtaining a pre-operative histological diagnosis in order to avoid under-treating high-grade or multifocal disease and over-treating low-grade disease, which could, in selected cases, be managed conservatively. We review nephroureterectomy at our institution over a 10-year period with particular reference to a pre-operative histological diagnosis. PATIENTS AND METHODS Nephroureterectomy was performed in 113 patients from February 1994 to February 2004. Of these cases, 58 were for upper tract TCC and 50 of these 58 had intravenous urography (IVU): 9 had only IVU, 28 had an additional CT scan, 5 had an additional ultrasonography and 8 had additional CT + ultrasonography for pre-operative work-up. Thirty-four of the 58 cases had retrograde pyelography. Nineteen (32.7%) of the 58 cases had a pre-operative ureteroscopy (URS) and biopsy; 14 of these had rigid URS for tumours in the lower (11) and middle (3) thirds of the ureter and 5 had flexible URS for pelvicalyceal tumours by an experienced endourologist. Thirty-one (53%) of the 58 tumours were within the pelvicalyceal system and 27 within the ureter (upper, 5; middle, 3; lower, 19). Forty-eight patients underwent a total nephroureterectomy: 40 had a two incision approach and 8 had an endoscopic resection of the lower ureter. Five of the 58 cases had a sub-total nephroureterectomy and 5 a laparoscopic nephroureterectomy with open excision of lower ureter. RESULTS Nineteen (32.7%) of the 58 patients had a pre-operative histological diagnosis - 17 G2pTa, 1 G1pTa, and 1 G2pT1. Fourteen (74%) biopsies matched the final postoperative histology, but 1 was down-staged, 3 up-staged and 1 up-graded compared to the original histology. Five (12.8%) of 39 patients without pre-operative histology had no TCC in the final surgical specimen: 4 (10.25%) had benign pathology such as capillary haemangioma, urothelial cysts and reactive urothelial changes while one had renal cell carcinoma (RCC). CONCLUSIONS This study underlines the importance of obtaining a pre-operative histological diagnosis in cases with presumed upper tract TCC. Failure to do so can result in unnecessary ablative surgery for benign disease. Such an approach can also help identify multifocality and grade of disease so that treatment of upper tract TCC can be tailored more appropriately with ablative surgery for high-grade or multifocal disease and conservative (endoscopic) therapy for low-grade disease in selected cases. Patients with suspected TCC of the upper tract should be managed at centres where facilities for the comprehensive evaluation of such tumours exist.

Abstract
PURPOSE To evaluate the oncologic results of our operative technique, hand-assisted retroperitoneoscopic nephroureterectomy (HRNU), for the treatment of upper-tract urothelial cancer, various perioperative parameters and oncologic outcomes were compared for HRNU and conventional open nephroureterectomy (CONU). PATIENTS AND METHODS Thirty-six patients with clinical stage T(1,2)N(0)M(0) renal-pelvic and ureteral tumors underwent HRNU. A retroperitoneoscopic nephrectomy was carried out with hand assistance via a lower-abdominal midline incision. The lower ureter was resected by open surgery through the same incision, and the operative specimen was extracted via the same incision. Thirty-seven cases of CONU were reviewed as historical controls. Various perioperative and parameters and oncologic results were compared for the two procedures. RESULTS The HRNU was completed in all but one case, which was converted to CONU. The mean operating time (395 minutes) was longer than that for CONU (289 minutes), and the mean estimated blood loss with HRNU (497 g) was greater than that with CONU (296 g). The mean time to oral intake (1.4 days) was shorter than that after CONU (2.3 days), and the mean time to walking was shorter (2.1 days v 2.6 days). There were no statistical differences in the cause-specific survival rate, the disease-free survival rate, or the bladder recurrence-free survival rate between HRNU (median follow-up 23 months) and CONU (median follow-up 56 months). CONCLUSION The HRNU, a combination of endoscopic and conventional open surgery, seems to be a reasonable surgical procedure, because the lower-abdominal incision can be utilized, not only as a route for hand assistance, but also as a window for open surgery when resecting the distal ureter as well as for extraction of surgical specimens. The procedure is a safe alternative to conventional open surgery for upper urinary-tract tumors from an oncologic viewpoint.

Abstract
OBJECTIVE To report our experience of laparoscopic nephroureterectomy and to compare our results to those published in the literature. PATIENTS AND METHOD Between 1997 and 2005, 15 laparoscopic nephroureterectomies were performed by 2 surgeons, in 12 men and 3 women for upper urinary tract transitional cell carcinoma. The mean age of the patients was 66 years. Three to five trocars were used depending on intraoperative findings in order to meet oncological imperatives: primary control of the renal pedicle before any contact with the tumour dissection in the plane of the radical nephrectomy. The operative specimen was extracted in a sealed bag via an infraumbilical mini-laparotomy that allowed pelvic ureterectomy and resection of the bladder cuff. RESULTS The mean operating time was 210 min. The procedure was converted to open lumbar laparotomy in 3 patients. The mean hospital stay was 13 days. The final histological stage showed 8 invasive tumours (pT2-pT3), 4 superficial tumours (pTa-pT1), 2 CIS and a benign tumour. Two patients died from local progression of the disease. The mean follow-up was 41 months (range: 12-96 months). CONCLUSION Laparoscopic nephroureterectomy for upper urinary tract transitional cell carcinoma, still under evaluation, is indicated in selected cases. Apart from patient selection, which remains difficult preoperatively, the cancer control results depend on compliance with the principles of this surgery.

Abstract
PURPOSE We have previously described our technique of combining HAL-NU using early ureteral ligation with simultaneous cystoscopic circumferential excision of the distal intramural ureter without primary closure of the bladder cuff. We report the oncological sequelae in patients who underwent HAL-NU using our technique of complete ureteral removal. MATERIALS AND METHODS We retrospectively evaluated all patients who underwent HAL-NU from April 1999 through July 2004. Cystograms were performed 1 week postoperatively in all patients. Pathological findings were reviewed. Cystoscopy was performed every 3 months to assess bladder recurrences. Upper tract imaging was performed postoperatively and then annually. The locations of recurrence and need for adjuvant treatment were assessed. RESULTS A total of 49 patients with an average age of 67 years underwent HAL-NU. Gravity cystography confirmed that bladder defects had completely sealed at 1 week in all patients. Mean followup was 10.6 months (median 10, range 1 to 52). Of the patients 20 (49%) had bladder tumors postoperatively. Two patients were found to have advanced stage disease, leading to chemotherapy with radiation therapy in 1 and radical cystectomy in the other at 4 and 14 months, respectively. A total of 25 patients had postoperative pelvic imaging. Four patients with pathological stage T2 (1) and T3 (3) had metastatic disease at followup. One patient was known to have pulmonary metastases preoperatively and HAL-NU was performed for refractory hematuria. Two patients were noted to have distant metastases to the liver, lung and bone at 1 and 3 months postoperatively, respectively. One patient was found to have distant metastases to the liver and retroperitoneal lymph nodes 2 years after surgery. No patients were found to have local pelvic or peritoneal metastases. CONCLUSIONS HAL-NU with cystoscopic excision of the distal ureter is feasible, safe and effective for upper tract transitional cell carcinoma. Oncological sequelae are comparable to results after open surgery. There is no evidence to suggest pelvic or peritoneal tumor seeding since no cases of pelvic or abdominal recurrence were discovered after surgery, while allowing the bladder defect to close spontaneously with catheter drainage. Our technique of ureterectomy ensures complete removal of the entire ureter, eliminating the possibility of ureteral stump recurrences. Early ligation of the ureter prevents tumor migration during renal manipulation, minimizing the risk of local tumor recurrences postoperatively.

Abstract
Various laparoscopic nephroureterectomy techniques for urothelial carcinoma of the upper urinary tract have been developed to minimize postoperative discomfort and the necessity for a lengthy convalescence. We performed hand-assisted retroperitoneoscopic nephroureterectomy without hand-assisted device in 3 male patients with urothelial carcinoma of the distal ureter. Average operative time and estimated blood loss were 251 min (range 235 to 280) and 250 mL (range 200 to 300), respectively. Complication did not occur and conversion to open surgery was not necessary in all cases. Postoperative analgesic requirements were moderate and the time to regular diet intake averaged 3 days (range 2 to 4). None of the patients had a positive margin on the final pathologic specimen. At the average follow-up of 8.1 months, no regional recurrence, port-site metastasis, bladder recurrence, or distant metastasis were noted in any patient. We described our initial experience with the described technique, which obviates the need for midprocedural patient repositioning.

Abstract
Advancements in minimally invasive instrumentation and technique have provided the impetus to performing urologic procedures with reduced perioperative morbidity, shorter hospital stays, and, most importantly, efficacious oncologic results. At multiple centers of excellence, laparoscopic nephroureterectomy (LNU) has evolved into a new standard for the management of upper-tract transitional-cell carcinoma (TCC) that is not amenable to endoscopic resection. An LNU may be performed via a transperitoneal or retroperitoneal approach together with excision of the distal ureter and a bladder cuff. Analysis of present-day studies comparing LNU with open techniques demonstrates equivalent oncologic outcomes. In addition, those patients undergoing LNU fare better than their counterparts having open surgery with respect to hospital stay, analgesic requirements, and convalescence. With multiple options for excision of a cuff of bladder, a consensus has not been established. However, LNU has emerged as the new standard of care for the treatment of upper- tract TCC. Review of the techniques and outcomes of LNU from the minimally invasive urology community are described.

Abstract
OBJECTIVES To report our experience with hand-assisted laparoscopic nephroureterectomy (HALNU) to treat upper urinary tract transitional cell carcinoma (TCC). In addition, we report the treatment of 4 patients with upper urinary tract TCC and synchronous superficial urinary bladder TCC by HALNU and simultaneous transurethral resection of bladder tumor (TURBT). METHODS We retrospectively reviewed 33 patients who had undergone HALNU. Recovery was evaluated according to the Eastern Cooperative Oncology Group performance status. Four patients had concomitant superficial urinary bladder cancer and underwent simultaneous TURBT at the beginning of surgery. We compared our data with those of our open surgery group and previously published data. RESULTS Partial recovery had occurred by 1 week and complete recovery by 4 weeks postoperatively. Conversion to open surgery was required in 2 (6%) of the 33 patients. The complication rate was 24% (8 of 33) without any mortality. The recurrence rate of urinary bladder TCC was 6% (2 of 33). Both patients with recurrent tumor were treated successfully by TURBT and bacille Calmette-Guérin instillation. All 4 patients with synchronous superficial urinary bladder TCC had undergone simultaneous transurethral resection of bladder tumor, and all 4 were disease free at the last follow-up visit. CONCLUSIONS Hand-assisted procedures are appropriate for surgeons with limited experience with laparoscopic surgery. In our study, the convalescence of patients was excellent, and the postoperative results were compatible with those of previous studies. To treat upper urinary tract TCC with synchronous urinary bladder TCC, HALNU and TURBT together seems to be a safe and efficient technique.

Abstract
PURPOSE To review the current literature and data describing primary endoscopic treatment of upper tract transitional cell carcinoma (TCC). MATERIALS AND METHODS Published, peer-reviewed articles on ureteroscopic, percutaneous, and laparoscopic treatment of upper tract TCC were identified using the MEDLINE database. RESULTS Nephroureterectomy has been considered the "gold standard" for upper tract TCC. Minimally invasive approaches, initially advocated for patients requiring a nephron sparing approach (i.e., solitary kidney or renal insufficiency) or those with significant comorbidities precluding definitive surgery, have been increasingly used with the further refinement of ureteroscopy, percutaneous renal surgery, and laparoscopy. Ureteroscopy has been used successfully, resulting in recurrence rates ranging from 31% to 65% and disease-free rates of 35% to 86%. Progression and metastatic rates are low and correlate with tumor grade. Likewise, percutaneous approaches show disease specific survival and recurrence rates correlating with tumor grade. Patients with low-grade tumors (Grades 1-2) do well with this approach with recurrence rates and disease specific survival rates of 26% to 28% and 96% to 100%, respectively. For those patients requiring complete extirpation of the kidney and ureter, laparoscopic nephroureterectomy results in decreased postoperative pain, shorter hospital stay, and more rapid convalescence without compromising cancer control. CONCLUSIONS Nephron sparing approaches in well-selected patients with low stage and low-grade disease can be treated endoscopically with ureteroscopy and percutaneous renal surgery. Laparoscopic nephroureterectomy offers a safe, minimally invasive alternative to traditional open surgical techniques for patients with TCC of the upper urinary tract.

Abstract
Surveillance of treated upper tract TCC must be tailored to each patient based on individual tumor characteristics. Important risk factors include tumor stage, grade, and multifocality. Molecular markers for TCC may assist in future surveillance strategies, but for now remain experimental. Improvements in imaging eventually may provide the sensitivity needed to determine tumor stage, which would make both initial and recurrence management decisions much more accurate. Initial surgical treatment will influence surveillance when it pertains to superficial disease treated conservatively with either open segmental resection or, now more commonly, with endoscopic resection. Patients treated in this manner require vigilant surveillance of the ipsilateral ureter. Direct visualization in combination with cytology currently appears to be the most effective method, using the same timelines as those used for bladder TCC. Prospective studies concerning surveillance protocols for upper tract TCC would certainly provide more evidence for the current recommendations. However, the evidence does show that upper tract TCC behaves biologically much in the same fashion as does bladder TCC. In light of this fact, the current recommendations are meant to suggest following a patient after treatment for upper tract TCC in a manner similar to that used to follow a patient after treatment of bladder TCC, with individual strategies based on tumor characteristics. For superficial disease, the technology now exists to moniter a patient after endoscopic resection of an upper tract tumor in exactly the same manner used to follow a patient after endoscopic resection of a bladder tumor.

Abstract
Transitional cell carcinoma (TCC) of ureter and renal pelvis is relatively uncommon. Smoking, occupational carcinogens, analgesic abuse, Balkan nephropathy are the risk factors. Cytogenetic studies revealed that the most frequent aberration is the partial or complete loss of chromosome 9. Approximately 20-50% of patients with upper urinary tract (UUT) TCC have bladder cancer at some point on their course, whereas the incidence of UUT TCC after primary bladder cancer is 0.7-4%. Excretory urography and retrograde pyelography are the conventional diagnostic tools; however, ureteropyeloscopy combined with cytology and biopsy is more accurate. Grade and stage of the disease have the most significant impact on survival. Nephroureterectomy with bladder cuff excision has been the mainstay of treatment. Local resection may be appropriate for distal ureteral lesions especially when the disease is low grade and stage. Advances in endourology have made it possible to treat many tumors conservatively. Ureteroscopic and to a certain extent percutaneous surgical approaches are widely used today especially in patients with low grade, low stage disease. Endoscopic close surveillance is mandatory for these patients. Adjuvant topical therapies appear to be safe but confirmation of any benefits awaits the results of further large studies. More recently, laparoscopic techniques have become a viable alternative to open surgery, but long term cancer control data are lacking. Aggressive surgical resection does not affect the outcome of patients with advanced disease. Adjuvant radiotherapy is ineffective, and systemic chemotherapy results in a low complete response rate for patients with metastases.

Abstract
BACKGROUND AND PURPOSE To assess the safety and feasibility of transcontinental telementored and telepresence surgery, we report on two procedures carried out with participation by surgeons in Baltimore in the United States and São Paulo and Recife in Brazil. PATIENTS AND METHODS Over a period of 3 months, a laparoscopic bilateral varicocelectomy and a percutaneous renal access for a percutaneous nephrolithotomy were performed. The mentoring surgeon (LRK) was the same for both procedures. He used a 650-MHz personal computer fitted with a Z360 video COder/ DECoder (CODEC) and a Z208 communication board (Zydacron Corp, Manchester, NH) that comprise the core of the telesurgical station. In the first case, a surgical robot, AESOP 3000 (Computer Motion Inc.), was attached to a laparoscope, and the remote surgeon drove the robot via a controller on the remote computer. In the second case, another robot (Percutaneous Access to the Kidney; PAKY) was used for percutaneous needle placement into the renal collecting system. RESULTS The two procedures were completed successfully. In the first case, the operative time was 25 minutes, with minimal estimated blood loss. The patient was discharged home the next day. At 3-month follow-up, there was no scrotal pain or varicocele. In the second case, access to the urinary tract was achieved with the first needle pass, and percutaneous nephrolithotomy was uneventful. Blood loss was minimal, and the patient was discharged home on the second postoperative day. At 3-month follow-up, the patient was free of urinary stones and of symptoms. CONCLUSIONS The first transcontinental telementored and telepresence urologic surgical procedures have been reported previously. The success observed with the novel surgical techniques has motivated great interest. The cases reported here demonstrate that several types of procedures can be mentored safely and effectively with telemedicine technology.

Abstract
PURPOSE We assessed the incidence of and analyzed factors that may help prevent major complications and open conversion during laparoscopic nephrectomy at our institutions. MATERIALS AND METHODS We retrospectively analyzed all laparoscopic nephrectomies performed between August 1, 1999 and July 31, 2001. Data were stratified for nephrectomy type, intraoperative and postoperative complications. Conversion to open surgery was stratified for emergency versus elective procedures. RESULTS Of the 292 laparoscopic procedures performed at our institutions in 2 years 213 (73%) involved laparoscopic nephrectomy, including 84 live donor nephrectomies, 61 radical nephrectomies, 55 simple nephrectomies and 13 nephroureterectomies. A total of 16 major complications (7.5%) occurred, including access related, intraoperative and postoperative complications in 3, 9 and 4 cases, respectively. The conversion rate was 6.1% (13 patients), the transfusion rate was 1.9% and the mortality rate was 0.5% (1 death). Only 1 complication was related to simple laparoscopic nephrectomy, although this group showed the highest rate of elective conversion (7 of 8 elective conversions). Laparoscopic live donor nephrectomy showed the highest rate for emergency conversion (3 of 5 emergency conversions). CONCLUSIONS Our results reinforce the importance of thorough preoperative imaging, careful patient selection, surgeon experience and skill maintenance in laparoscopy as well as a low threshold for conversion to open surgery. This series provides additional evidence to support the evolution of laparoscopic nephrectomy into a standard of care.

Abstract
PURPOSE We present a novel method of kidney retrieval based on a modified Pfannenstiel incision and insertion of the assistant hand into the abdominal cavity without a device for pneumoperitoneum preservation. This maneuver is performed as the last step in pure laparoscopic live donor nephrectomy. Also, we assessed the effect of this technique on warm ischemia time compared with the standard laparoscopic bag retrieval technique. MATERIALS AND METHODS A total of 70 laparoscopic live donor nephrectomies were performed at our institutions between October 1998 and March 2001. The first 43 cases were completed using an EndoCatch bag device (Auto Suture, Norwalk, Connecticut) for specimen retrieval, while the last 27 were done using a novel manual retrieval technique through a modified Pfannenstiel incision. We retrospectively analyzed the results in regard to warm ischemia time and intraoperative complications related to the procedure. RESULTS A statistically significant difference was noted in the EndoCatch and manual retrieval groups in regard to warm ischemia time (p <0.001). There were 2 complications related to the EndoCatch device and none related to the manual technique. No differences were detected regarding recipient outcomes. CONCLUSIONS Manual specimen retrieval after live donor nephrectomy allows shorter warm ischemia time, while saving the cost of an EndoCatch bag or pneumoperitoneum preserving device that would be used during hand assisted live donor nephrectomy. It was shown to be a safe method without increased donor morbidity.

Abstract
OBJECTIVES To summarize the results of our 31 consecutive laparoscopic nephrectomies for renal tuberculosis and compare them with 45 laparoscopic nephrectomies performed for other benign etiologies. We previously reported our initial successful experiences in expanding the role of laparoscopic surgery with the introduction of laparoscopic nephrectomy for renal tuberculosis. METHODS Thirty-one laparoscopic nephrectomies for renal tuberculosis were performed between June 1996 and December 2001. The patients consisted of 11 men and 20 women with a mean age of 44.2 years (range 29 to 64). The control group consisted of 17 men and 28 women with a mean age of 48.6 years (range 17 to 60). The two groups were comparable with regard to demographic data. Statistical analyses were used to compare the two groups in terms of various parameters, including surgical time, blood loss, analgesic requirements, resumption of oral intake, and hospital stay. RESULTS Laparoscopic nephrectomy was successful in 30 cases of the tuberculosis group and 44 cases of the control group. The two groups showed comparable perioperative and postoperative parameters, except for mean operative time, which, at 244 minutes for the tuberculosis group, was significantly greater than the 216 minutes for the control group (P <0.05). No significant intraoperative or postoperative complications were observed in either group. CONCLUSIONS The results of this study indicate that laparoscopic nephrectomy for renal tuberculosis is a safe, effective, and less invasive treatment modality. Therefore, we suggest that the renal tuberculous nonfunctioning kidney should be approached initially using the laparoscopic approach.

Abstract
Until recently, malignancies of the kidney and ureter were managed with open radical surgery. Over the last decade the urologic community has adopted the skill of laparoscopic surgery for the treatment of these tumours. Parenchymal sparing procedures have become the standard of care in the treatment of selected patients with renal and ureteral tumours and many of these surgical procedures can be performed laparoscopically or ureteroscopically. Due partly to necessity and partly to the advancement of technology, renal and ureteral sparing procedures have become commonplace for definitive treatment and palliation of these tumours. The morbidity of such procedures is significantly less than for open surgery and the future of urologic minimally invasive surgery appears secure. This review article is aimed at updating the reader in the most recent advances in these techniques.

Abstract
Objectives. To report a modified approach for hand-assisted laparoscopic nephroureterectomy (HALNU).Methods. Seven patients with localized transitional cell carcinoma of the upper urinary tract underwent unilateral HALNU. Patients were placed in a 60 degrees oblique position during the entire procedure. Via a 7-cm Gibson incision on the lesion side, the distal ureterectomy and bladder cuff excision were done by an open method without opening the bladder. Then, with the surgeon's hand inserted into the peritoneal cavity by way of the same wound, HALNU was performed with two to three additional laparoscopic ports. The perioperative parameters were compared with those of 15 cases of conventional open nephroureterectomy.Results. Patients in the HALNU group had significantly less mean blood loss (140 versus 455 mL) and earlier resumption of oral intake (33 versus 61 hours), required fewer narcotics (38 versus 70 mg of morphine sulfate equivalent), and were discharged earlier (7.33 versus 9.1 days), with a faster convalescence to normal activity (3.7 versus 5.6 weeks; all P < 0.05). The total mean surgical time was 3.7 hours for the HALNU group.Conclusions. Our approach used the same incision to both excise the distal ureter and apply the hand-assist device. It also preserved the benefits of the minimal invasiveness of laparoscopic surgery compared with its open counterpart.
