Who is at risk of death from nephrectomy? An analysis of thirty-day mortality after 21 380 nephrectomies in 3 years of the British Association of Urological Surgeons (BAUS) National Nephrectomy Audit.

OBJECTIVE: To ascertain contemporary overall and differential thirty-day mortality (TDM) rates after all types of nephrectomy in the UK, and to identify potential new risk factors for death. PATIENTS AND METHODS: We conducted a retrospective analysis of the 110 deaths that occurred within 30 days of surgery out of the total of 21 380 nephrectomies performed, and calculated the odds ratio (OR) and 95% confidence interval (CI) for TDM based on peri-operative characteristics. RESULTS: The overall TDM rate was 110/21380 (0.5%). The TDM rates after radical, partial, simple nephrectomy and nephro-ureterectomy were 0.6% (63/11057), 0.1% (4/3931), 0.4% (11/2819) and 0.9% (28/3091), respectively. TDM increased with age, stage, estimated blood loss (EBL), operating time and performance status. EBL of 1-2 L was associated with a greater risk of TDM than EBL of 2-5 L (OR 1.38; 95% CI 1.03-2.24). Conversion from minimally invasive surgery was associated with higher risk than non-conversion (OR 2.53; 95% CI 1.14-4.51. Curative surgery was safer than cytoreductive surgery (OR 0.31; 95% CI 0.18-0.54). There was an association between surgical volume and TDM. CONCLUSIONS: This study provides contemporary insights into the true risks of all types of nephrectomy. The TDM rate after nephrectomy in the UK appears acceptably low at 0.5%. Established risk factors were confirmed and the following novel risk factors were identified: modest EBL (1-2 L) and conversion from minimally invasive surgery.

Pelvic ureteral angiomyoma mimicking urothelial carcinoma: A case report.

BACKGROUND: Angiomyoma is a rare benign tumor that can occur in any organ with smooth muscles. No one has already described an angiomyoma of the ureter. CASE PRESENTATION: We report the case of a 44 year old woman who presented with intermittent hematuria and left flank pain. The diagnosis of left ureteral tumor was evoked by the scannographic aspect. She underwent a radical nephro-ureterectomy. Final histological examination concluded to ureteral angiomyoma. DISCUSSION: Angiomyoma is rare benign smooth muscle tumor with a vascular component. Symptomatology depends on the organ that angiomyoma is developed from, and is usually mimicking malignant tumors. CONCLUSION: Symptomatology, radiologic findings are mimicking urothelial carcinomas, however the pathology corrected the diagnostic error.

Bladder endometriosis: A serious disease.

Urinary tract endometriosis (UTE) is a very rare but serious form of infiltrating endometriosis because of the risk of urinary tract obstruction and loss of renal function. We report the case of A 42-year-old female patient admitted for intense right back pain with lower urinary tract disorders. An abdomino-pelvic ultrasound was done showing right uretero-hydronephrosis. Ureteroscopy showed an inflammatory-like stenosis of the right pelvic ureter. Given the young age of the patient, the poor quality of the right kidney, we opted for a right total nephro ureterectomy. The anatomopathological examination showed a bladder endometriosis .

A low psoas muscle volume predicts longer hospitalization and cancer recurrence in upper urinary tract urothelial carcinoma.

The aging population is becoming a primary global problem. The most important alteration that occurs in the body with age, is the loss of skeletal muscle. Previously, sarcopenia, which is associated with the loss of skeletal muscle, has been reported to be associated with the prognosis of cancer and complications. The present study investigated the importance of sarcopenia with regard to the prognosis or postoperative complications of upper urothelial cancer patients who underwent nephro-ureterectomy. A total of sixty patients (male, n=44; female, n=16) underwent nephro-ureterectomy for upper urothelial carcinoma. The psoas muscle volume was calculated at the level of the umbilicus using axial computed tomography images obtained prior to nephro-ureterectomy. The psoas muscle index (PMI) was calculated by the following formula: (right side psoas muscle area at the level of the umbilicus mm2)/(body height m)2. The median and mean (± standard deviation) ages of the 44 patients were 71 and 68.0 years (± 12.2 years). The lower PMI group demonstrated a significantly poorer recurrence-free survival compared with the higher PMI group (634 vs. 2,317 days, P=0.005). In terms of the duration of postoperative admission, the long-admission group (≥13 days) demonstrated a significantly lower PMI compared with the short-admission group (≤12 days) (383.0 vs. 433.1, P=0.039). Although the overall survival of the two groups did not differ significantly, the lower PMI group tended to have a shorter survival period compared with the higher PMI group (P=0.080). Of the patients with upper urothelial carcinoma, the lower PMI group exhibited a longer postoperative admission period and poorer recurrence-free survival compared with the higher PMI group. The present findings suggest that sarcopenia is a meaningful factor that should be considered when selecting therapy for upper urothelial carcinoma.

Reduce bladder cancer recurrence in patients treated for upper urinary tract urothelial carcinoma: The REBACARE-trial.

BACKGROUND: Following radical nephro-ureterectomy for urothelial carcinoma of the upper urinary tract (UUT), the reported bladder recurrence rate of urothelial carcinoma is 22-47%. A single intravesical instillation of chemotherapy within 10 days following nephro-ureterectomy has the potential to decrease the risk of a bladder recurrence significantly. Despite recommendation by the European Association of Urology guideline to administer a single instillation postoperatively, the compliance rate is low because the risk of extravasation of chemotherapy. AIM: To reduce the risk of bladder cancer recurrence by a single intravesical instillation of Mitomycin immediately (within 3 h) before radical nephro-ureterectomy or partial ureterectomy. METHODS: Adult patients (age ≥ 18 years) with a (suspicion of a) urothelial carcinoma of the UUT undergoing radical nephro-ureterectomy or partial ureterectomy will be eligible and will receive a single intravesical instillation of Mitomycin within 3 h before surgery. In total, 170 patients will be included in this prospective, observational study. Follow-up will be according to current guidelines. RESULTS: The primary endpoint is the bladder cancer recurrence rate up to two years after surgery. Secondary endpoints are: a) the compliance rate; b) oncological outcome; c) possible side-effects; d) the quality of life; e) the calculation of costs of a single neoadjuvant instillation with Mitomycin and f) molecular characterization of UUT tumors and intravesical recurrences. CONCLUSIONS: A single intravesical instillation of Mitomycin before radical nephro-ureterectomy or partial ureterectomy may reduce the risk of a bladder recurrence in patients treated for UUT urothelial carcinoma and will circumvent the disadvantages of current therapy.

Techniques and Outcomes of Robot-assisted Nephro-ureterectomy for Upper Tract Urothelial Carcinoma.

Radical nephro-ureterectomy and bladder cuff excision (RNUBCE) is the gold standard treatment for upper tract urothelial carcinoma (UTUC). RNUBCE can be performed via an open, laparoscopic or robot-assisted approach. The primary objective of this narrative mini-review is to report the techniques and outcomes for robot-assisted RNUBCE in the published literature. Relevant articles were selected utilizing the following search categories: "robot nephro-ureterectomy", "robot-assisted nephro-ureterectomy", and "robot upper tract urothelial carcinoma". Different techniques in terms of patient positioning, port placement, lymph node dissection, and bladder cuff excision have been reported in the literature. Despite these varied techniques, perioperative outcomes of robot-assisted laparoscopic RNUBCE are favorable. In all, a total of 204 patients underwent RNUBCE, with a mean operating room time of 229.7min, mean blood loss of 189ml, and mean length of stay of 3.65 d. Further studies are needed to validate oncologic outcomes. PATIENT SUMMARY: Patients with high-risk upper tract urothelial carcinoma require complete removal of the kidney, ureter, and bladder cuff, along with a lymph node dissection. Although the procedure can be performed via an open approach, minimally-invasive surgery represents an alternative. Herein, we describe the techniques and outcomes of robot-assisted radical nephro-ureterectomy and bladder cuff excision.

Evaluation and outcome of the distal ureteral stump after nephro-ureterectomy in children. A comparison between laparoscopy and retroperitoneoscopy.

BACKGROUND: In children with a poorly functioning kidney due to vesicoureteral reflux (VUR) or ureteropelvic junction obstruction, management is by nephrectomy with total or proximal ureterectomy. The complete removal of all the ureter minimizes the risk of future morbidity associated with the distal ureteral stump (DUS), including febrile urinary tract infections (UTIs), lower quadrant pain and hematuria, the so-called ureteral stump syndrome. OBJECTIVE: To assess the outcome of the DUS after nephroureterectomy, we analyzed our recent experience of nephrectomy performed via retroperitoneoscopy and via laparoscopy. METHODS: The records of 21 consecutive patients (median age 3.5 years, range 1-10 years) who underwent nephroureterectomy via laparoscopy or via retroperitoneoscopy were retrospectively reviewed for symptoms caused by DUS and their management. Nephrectomy was undertaken for a poorly functioning dysplastic (4), scarred from VUR (10) or hydronephrotic (7) kidney. In the laparoscopic group (11 pts), 6 cases required nephrectomy for reflux while 5 patients were operated for hydronephrotic or dysplastic non-functioning kidney. In the retroperitoneoscopic group (10 pts), nephrectomy was performed for reflux in 4 cases versus 6 patients affected by hydronephrotic or dysplastic non-functioning kidney. The patients were evaluated using ultrasound (US) to check DUS length and clinically to evaluate symptoms due to a symptomatic DUS. RESULTS: The average length of surgery was 50 min for laparoscopy and 80 min for retroperitoneoscopy. The average of follow-up was 5 years. The length of DUS after laparoscopic nephrectomy was shorter (range 3-7 mm, statistically significant) than the DUS after retroperitoneoscopy (range 2-5 cm) (p < 0.001). Laparoscopic patients were all asymptomatic. Two patients, after retroperitoneoscopic nephrectomy, presented with recurrent UTIs; a voiding cystography revealed a VUR on the residual DUS and a redo surgery was performed in both the patients to remove the DUS (Figure). DISCUSSION: Several authors have stated that, in case of subtotal ureterectomy, the incidence of symptomatic DUS after nephrectomy for high-grade vesicoureteric reflux is low. However, in our series, the incidence of symptomatic DUS after nephroureterectomy was not insignificant (2/21, 9.5%). Symptoms related to a refluxing DUS occurred only in patients undergoing retroperitoneoscopic nephroureterectomy, where the DUS was longer than the DUS detected in laparoscopic patients. CONCLUSIONS: Considering that laparoscopy permits removal of all the ureter near the bladder dome, in children with non-functioning kidney due to VUR, it is advisable to always perform a laparoscopic rather than a retroperitoneoscopic nephrectomy to prevent problems related to a symptomatic DUS.

Simultaneous en-bloc robot-assisted radical cystectomy and nephro-ureterectomy: technique description, outcomes, and literature summary.

The objectives of this study are to describe the surgical technique for simultaneous en-bloc robot-assisted radical cystectomy and nephro-ureterectomy, to report its surgical bench marks, and finally, to summarize the current evidence on the procedure. After written informed consent, we prospectively enrolled consecutive patients undergoing simultaneous en-bloc robot-assisted radical cystectomy and nephro-ureterectomy in a prospective institutional database. We performed all procedures with robotic assistance from the DaVinci Si-HD®, a four-arm robotic system. Endpoints included surgery duration, estimated intra-operative blood loss, resection margins, intra-, and post-operative complications. Furthermore, we describe oncological outcome at follow-up. We conducted six (54.4 %) right-sided and five (45.5 %) left-sided nephro-ureterectomies. Urinary diversion consisted in nine (81.2 %) ureterocutaneostomies and in two (18.8 %) ileum conduits. The median surgery duration was 287 min [interquartile range (Q1-Q3) 253-328], thereof 196-min console time (Q1-Q3 158-230). The median-estimated blood loss was 235 mL (Q1-Q3 200-262). We did not register any intra-operative complications or conversions to open surgery. Post-operatively, each one patient suffered a Clavien-Dindo grade 1 (paralytic ileus), grade 2 (blood transfusion), and grade 3 complication (port hernia). After a median follow-up of 7 months (Q1-Q3 4-25), we registered one recurrence, a metachronous transitional cell cancer of the contralateral kidney 24 months after the initial procedure. En-bloc robot-assisted radical cystectomy and nephro-ureterectomy was associated with limited procedure duration, minor blood loss and satisfying intra- and post-operative outcomes.

"The Lister Technique": a new technique for the management of the distal ureter during radical robotic nephroureterectomy.

We describe "The Lister Technique"-a new 3 step procedure developed in our department for robotic assisted laparoscopic nephroureterectomy (RANU). Our new technique facilitates the complete excision of the whole ureter including ureteric orifice and reduces this risk of tumour spillage from the distal ureter without the need for bivalving the bladder. Our initial data indicates that the technique is associated with reduction in bladder recurrence post-operatively in comparison to current published series. Longer follow up and larger patient numbers are required to validate these results further.

Multifocality rather than tumor location is a prognostic factor in upper tract urothelial carcinoma.

OBJECTIVES: Whether a patient has urothelial carcinoma located within the renal pelvis or ureter remains a controversial prognostic indicator in clinical urology. We wished to evaluate whether tumor location is associated with recurrence in patients undergoing nephroureterectomy for upper tract urothelial cancer in a large volume patient cohort. SUBJECTS AND METHODS: We created a retrospective database of patients from 7 academic centers throughout Canada who underwent nephroureterectomy for upper tract urothelial carcinoma. Patient demographics as well as pathologic and surgical factors were analyzed to evaluate any statistical association between tumor location and overall survival, disease-free survival, and disease-specific survival. RESULTS: A total of 1,029 patients had data available for analysis with a mean follow up of 3.2 years. Kaplan Meier 5-year disease-free survivals (DFS) were 46%, 37%, and 19% for renal pelvis tumors, ureteric tumors, and multifocal tumors respectively. There was no association between the location of the tumor and the DFS, however, disease involving both the ureter and renal pelvis was associated with lower DFS and overall survival (OS) (P < 0.001). CONCLUSIONS: Tumor location does not appear to have any influence on the risk of recurrence of disease following nephroureterectomy in this large patient cohort. However, multifocal tumors involving both the ureter and renal pelvis had a significantly worse prognosis and should be considered for more aggressive management.
