Development and Validation of a Preoperative Nomogram for Endoscopic Management Decision Making in Upper Urinary Tract Urothelial Carcinoma.

OBJECTIVE: We aimed to develop and validate a preoperative nomogram that predicts low-grade, non-muscle invasive upper urinary tract urothelial carcinoma (LG-NMI UTUC), thereby aiding in the accurate selection of endoscopic management (EM) candidates. METHODS: This was a retrospective study that included 454 patients who underwent radical surgery (Cohort 1 and Cohort 2), and 26 patients who received EM (Cohort 3). Utilizing a multivariate logistic regression model, a nomogram predicting LG-NMI UTUC was developed based on data from Cohort 1. The nomogram's accuracy was compared with conventional European Association of Urology (EAU) and National Comprehensive Cancer Network (NCCN) models. External validation was performed using Cohort 2 data, and the nomogram's prognostic value was evaluated via disease progression metrics in Cohort 3. RESULTS: In Cohort 1, multivariate analyses highlighted the absence of invasive disease on imaging (odds ratio [OR] 7.04; p = 0.011), absence of hydronephrosis (OR 2.06; p = 0.027), papillary architecture (OR 24.9; p < 0.001), and lack of high-grade urine cytology (OR 0.22; p < 0.001) as independent predictive factors for LG-NMI disease. The nomogram outperformed the two conventional models in predictive accuracy (0.869 vs. 0.759-0.821) and exhibited a higher net benefit in decision curve analysis. The model's clinical efficacy was corroborated in Cohort 2. Moreover, the nomogram stratified disease progression-free survival rates in Cohort 3. CONCLUSION: Our nomogram ( https://kmur.shinyapps.io/UTUC_URS/ ) accurately predicts LG-NMI UTUC, thereby identifying suitable candidates for EM. Additionally, the model serves as a useful tool for prognostic stratification in patients undergoing EM.

Prostate-specific antigen density during dutasteride treatment for 1 year predicts the presence of prostate cancer in benign prostatic hyperplasia after the first negative biopsy (PREDICT study).

OBJECTIVES: To prospectively evaluate the detection rate of prostate cancer, and to identify the risk factors of prostate cancer detection after a 1-year administration of dutasteride and first negative prostate biopsy. METHODS: Patients with benign prostatic hyperplasia who presented high prostate-specific antigen levels after the first negative prostate biopsy were administered 0.5 mg dutasteride daily for 1 year. They underwent a repeat prostate biopsy after 1 year. The primary end-point was the detection rate of prostate cancer. The secondary end-point was the ability of prostate-specific antigen kinetics to predict prostate cancer detection. Prostate-specific antigen was measured before the initial prostate biopsy and at 6, 9 and 12 months after starting dutasteride. Patients were classified into a prostate cancer and a non-prostate cancer group. RESULTS: Prostate cancer was detected in 15 of 149 participants (10.1%). The total prostate-specific antigen change between the prostate cancer and non-prostate cancer group at 1 year was significantly different (P = 0.002). Although prostate-specific antigen levels at baseline did not significantly differ between study groups (P = 0.102), prostate-specific antigen levels at 6, 9 and 12 months were significantly different (P = 0.002, P = 0.001 and P < 0.001, respectively). The mean reduction rate of prostate-specific antigen density between the prostate cancer and non-prostate cancer group at 1 year was significantly different (-4.25 ± 76.5% vs -38.0 ± 28.7%, P = 0.001). Using a multivariate analysis, a >10% increase of prostate-specific antigen density at 1 year post-dutasteride treatment was the only predictive risk factor for prostate cancer after the first negative prostate biopsy (odds ratio 11.238, 95% confidence interval 3.112-40.577, P < 0.001). CONCLUSION: In the present study cohort, >10% increase in prostate-specific antigen density represented the only significant predictive risk factor for prostate cancer diagnosis in patients with elevated prostate-specific antigen after the first negative prostate biopsy.

Efficacy and Safety of Complete Intraureteral Stent Placement versus Conventional Stent Placement in Relieving Ureteral Stent Related Symptoms: A Randomized, Prospective, Single Blind, Multicenter Clinical Trial.

PURPOSE: We compared the efficacy and safety of complete and conventional stent placement to relieve ureteral stent related symptoms. MATERIALS AND METHODS: We randomized 85 patients who required ureteral stent placement after lithotripsy into an intraureteral or a conventional stent placement group. The ureteral stent remained in place until postoperative day 14. We evaluated scores on the visual analog scale pain, the SF-36 (36-Item Short-Form Health Survey), the I-PSS (International Prostate Symptom Score) and the OABSS (Overactive Bladder Symptom Score) on postoperative days 3 and 14. We also assessed the total amount of analgesics administered and stent related complications. RESULTS: Overall the records of 80 patients were analyzed. Pain scores were significantly lower in the intraureteral vs the conventional stent placement group (postoperative days 3 and 14, 4.85 vs 9.78, p = 0.003, and 3.15 vs 6.20, p = 0.014, respectively). The total I-PSS score (postoperative days 3 and 14, 10.41 vs 14.90, p = 0.006, and 11.67 vs 16.10, p = 0.022, respectively) and total analgesic use (19.23 vs 88.54 mg, p <0.001) were significantly lower in the intraureteral group. However, differences in the SF-36 and the total OABSS scores did not significantly differ. On subgroup analysis the pain score in the groin and bladder areas, incomplete emptying and daytime frequency on the I-PSS, the quality of life index and daytime frequency on the OABSS were significantly better in the intraureteral stent placement group than the conventional stent placement group on postoperative days 3 and 14 (all p <0.05). There was no difference in the complication rate between the 2 groups. CONCLUSIONS: Intraureteral stent placement may be associated with less ureteral stent related discomfort than conventional stent placement. This novel placement method is feasible and safe, and it can be immediately used in daily clinical practice.

Impact of ureteric stent removal by string on patient's quality of life and on complications at post-ureteroscopy for urolithiasis: a controlled trial.

OBJECTIVES: To evaluate the impact of ureteric stent removal by string vs ureteric stent removal by cystoscope with regard to pain at ureteric stent removal, complications and quality of life, as well as patients' self-rated symptoms, after ureteroscopy (URS) for urolithiasis. PATIENTS AND METHODS: Of 328 patients who underwent URS for upper urinary tract stones at our institution, 149 were randomly divided into a ureteric stent removal by string group (string group) and a ureteric stent removal by flexible cystoscope group (cystoscope group), using gender as a stratification factor. We focused on four sites, namely, the upper abdomen, bladder, flank and urethra, to evaluate the most painful site at stent removal. The primary endpoint was total pain scores for four sites at stent removal in the string group vs the cystoscope group. Secondary endpoints included comparison of the psychological well-being scores of patients using the five-item World Health Organization well-being index (WHO-5) preoperatively, pre-stent removal and 2 weeks after stent removal between the string group and cystoscope group. RESULTS: Of 149 patients analysed, 74 were in the string group and 75 were in the cystoscope group. In most patients, the ureteric stent was removed ~10 days after URS. The string group experienced significantly less pain than the cystoscope group (mean visual analogue scale [VAS] scores 2.73 vs 5.67; P < 0.001). Although VAS scores for women were not significantly different between the groups (P = 0.300), those for men were significantly lower in the string group (P < 0.001). In particular, men in the string group experienced significantly less urethral pain than those in the cystoscope group. The WHO-5 scores were not significantly different between the groups preoperatively, pre-stent removal or 2 weeks after stent removal. Stent string-related complications and self-rated symptoms were also not significantly different. CONCLUSION: Ureteric stent removal by string after URS led to significantly less pain than removal by cystoscope in men. Patients in the string group experienced no more complications in terms of urinary tract infections or accidental dislodgement than those in the cytoscope group.

Prognostic Impact of Renin-Angiotensin Inhibitors in Patients with Bladder Cancer Undergoing Radical Cystectomy.

BACKGROUND: Renin-angiotensin system blockade has been effective for the treatment of patients with several types of malignancy. This study evaluated the prognostic impact of renin-angiotensin system inhibitors, including angiotensin-2 converting enzyme inhibitors and angiotensin 2 receptor blockers, in patients with bladder cancer undergoing radical cystectomy. METHODS: This retrospective study included 269 patients who had undergone radical cystectomy. The oncologic outcomes of patients treated or not treated with renin-angiotensin system inhibitors after surgery were evaluated. Overall survival and cancer-specific survival were assessed by the Kaplan-Meier method and by Cox regression analysis. RESULTS: The median follow-up duration after radical cystectomy in survivors was 44.5 months. The 5-year, cancer-specific survival rates in patients who did and did not receive renin-angiotensin system inhibitors were 79.0 and 66.4 %, respectively (P = 0.011). Similarly, the 5-year overall survival rates were 76.1 and 61.4 %, respectively (P = 0.0097). Multivariable analyses showed that use of renin-angiotensin system inhibitors was an independent prognostic factor for cancer-specific survival (hazard ratio 0.47, P = 0.036) and for overall survival (hazard ratio 0.36, P = 0.022). CONCLUSIONS: Renin-angiotensin system inhibitors significantly reduced the risks of cancer-specific and overall mortality after radical cystectomy in patients with bladder cancer. Renin-angiotensin system inhibitors may improve oncologic outcomes in high-risk patients with bladder cancer.

[Improvement in Hyperglysemia Following Unilateral Adrenalectomy for ACTH-Independent Macronodular Adrenal Hyperplasia (AIMAH) : A Case Report].

Adrenal corticotropin (ACTH) -independent macronodular adrenal hyperplasia (AIMAH) is a rare cause of Cushing's syndrome. Bilateral adrenalectomy is the treatment of choice, but lifetime steroid replacement is essential. Here we report a case of AIMAH whose hyperglycemia was improved following unilateral adrenalectomy. A 42-year-old woman with serious intellectual disability and intractable epilepsy presented with polydipsia. Casual blood glucose and hemoglobin A1c (HbA1c) were 322 mg/dl and 8.5%, respectively. The cortisol level was high and ACTH level was low. Abdominal computed tomography and magnetic resonance imaging revealed unsuspected macronodular enlargement of bilateral adrenal glands (left 8 cm, right 4 cm in maximal diameter) and she was diagnosed with AIMAH. Both adrenal glands showed intense 131 I-adosterol accumulation predominantly in the left side and left-unilateral laparoscopic adrenalectomy was performed. Both insulin and oral antidiabetic drugs could be cancelled postoperatively, and HbA1c decreased to 5.7%. Steroid was not replaced but she never experienced adrenal crisis. We conclude that unilateral adrenalectomy is a safe and effective treatment for certain cases of AIMAH.

Prognostic impact of perioperative lymphocyte-monocyte ratio in patients with bladder cancer undergoing radical cystectomy.

Various systemic inflammatory response biomarkers are associated with oncological outcome. We evaluated the superiority of prognostic predictive accuracy between neutrophil-lymphocyte ratio (NLR) and lymphocyte-monocyte ratio (LMR), and the prognostic significance of their perioperative change in patients with bladder cancer undergoing radical cystectomy (RC). We retrospectively analyzed 302 patients who had undergone RC in four institutions. Comparison of predictive accuracy between NLR and LMR was performed using receiver operating characteristic curve analysis. Overall survival (OS) and cancer-specific survival (CSS) were assessed with the Kaplan-Meier method and Cox regression analysis. Preoperative and postoperative LMR showed higher predictive accuracy for OS than NLR did (p = 0.034). Applying a cutoff of 3.41, change in perioperative LMR stratified patients into three groups (low, intermediate, and high risk), showing a significant difference in OS and CSS (p < 0.001, each), and pathological outcomes. Multivariable analyses for OS and CSS showed that poor changes in LMR (high risk) were an independent prognostic factor (hazard ratio 5.70, 95 % confidence interval 3.49-9.32, p < 0.001; hazard ratio 4.53, 95 % confidence interval 2.63-7.82, p < 0.001; respectively). Perioperative LMR is significantly associated with survival in patients with bladder cancer after RC, and it is possibly superior to NLR as a prognostic factor.

Perioperative change in neutrophil-lymphocyte ratio predicts the overall survival of patients with bladder cancer undergoing radical cystectomy.

OBJECTIVE: To assess the prognostic value of perioperative changes in the neutrophil-lymphocyte ratio in patients with bladder cancer undergoing radical cystectomy. METHODS: We performed a retrospective analysis of 323 patients who had undergone radical cystectomy at our institutions. Overall survival was assessed with the Kaplan-Meier method and Cox regression analysis. RESULTS: Preoperative and postoperative neutrophil-lymphocyte ratios were significantly correlated with overall survival (both P = 0.0001). Changes in perioperative neutrophil-lymphocyte ratio stratified the patients into two groups, designated favorable- and poor-risk groups, with significantly different 5-year overall survival rates (75.1% and 41.4%, respectively; P < 0.0001). Multivariate Cox regression analyses showed that the perioperative change in neutrophil-lymphocyte ratio was an independent prognostic factor for overall survival (hazard ratio 2.56, 95% confidence interval 1.75-3.73; P < 0.001). Moreover, a decrease in neutrophil-lymphocyte ratio after adjuvant chemotherapy was associated with favorable overall survival in patients with high postoperative neutrophil-lymphocyte ratio (P < 0.001), indicating that neutrophil-lymphocyte ratio may be a predictive factor for the efficacy of adjuvant chemotherapy. CONCLUSIONS: Perioperative changes in neutrophil-lymphocyte ratio are significantly associated with overall survival in patients with bladder cancer undergoing radical cystectomy. Follow-up of the neutrophil-lymphocyte ratio change may be useful for the clinical management of patients after surgery.

[A Case of Traumatic Dislocation of the Penis].

We report a rare case of a traumatic dislocation of the penis. The patient was a 39-year-old man who was ambulanced to our hospital because of a motorbike accident. He was diagnosed to have a pelvic fracture. He was admitted to our department because of his urinary retention and lower abdominal pain. Only the penile skin was left as the genital organ, and neither the penis nor the glans penis was palpable. As the computed tomography scan of the abdomen revealed the dislocation of the penis under the skin in the foreside of the pubic bone, urinary retention due to the traumatic dislocation of the penis was diagnosed, and a percutaneous cystostomy was performed. After improvement of his general condition, the patient was transferred to our department for the evaluation of the perineal region, including the lower urinary tract, and for the treatment of the traumatic dislocation of the penis. First, as hematoma and abscess in the left spermatic cord were suspected by magnetic resonance imaging of the pelvic region, removal of the hematoma and abscess in the left spermatic cord as well as an anterograde cystoscopy were performed under lumbar anesthesia, and the absence of urethral injury was confirmed. After infection control, repositioning of the penis was jointly performed with the Department of Plastic Surgery of our hospital under general anesthesia. After the operation, spontaneous urination was observed and erectile function was observed to be normal.

A novel risk stratification model, involving preoperative lymphocyte-monocyte ratio and standard pathological factors, for overall survival in patients with bladder cancer undergoing radical cystectomy.

OBJECTIVE: To evaluate the ability of preoperative lymphocyte-monocyte ratio to predict prognosis and determine post-operative risk stratification in patients with bladder cancer undergoing radical cystectomy. METHODS: A retrospective review of the 210 patients who had undergone radical cystectomy for bladder cancer from 2006 to 2013 identified 181 patients with sufficient data to evaluate the prognostic significance of the lymphocyte-monocyte ratio. Overall survival was assessed by the Kaplan-Meier method. The association of clinicopathological findings with overall survival was evaluated by a multivariate Cox proportional model, and a novel risk stratification model to predict prognosis was established. RESULTS: Median follow-up after radical cystectomy was 6.0 years. The 5-year overall survival rate was significantly lower for patients with low than high lymphocyte-monocyte ratio (27.6 vs 80.7%, P < 0.001). Multivariable analyses showed that pT ≥2, pN ≥1, positive margins and low lymphocyte-monocyte ratio were independent predictors of overall survival. A post-operative risk stratification model using these factors showed significant differences among the three subgroups (low, intermediate and high risk) with a concordance index of 0.84. The 5-year overall survival rates in patients at low, intermediate and high risk were 85.4, 45.5 and 0%, respectively (P < 0.001). CONCLUSIONS: Preoperative lymphocyte-monocyte ratio, pathological tumor and lymph node stage and positive margins are significantly associated with overall survival in patients who have undergone radical cystectomy for bladder cancer.

Preliminary report: nephroscope-assisted "pulling-thread" technique for placement of peritoneal dialysis catheter.

BACKGROUND: Several catheter placement procedures have been described for initiation of peritoneal dialysis, including percutaneous insertion, open surgery, and laparoscopic surgery. However, the optimal approach to catheter placement for peritoneal dialysis remains controversial, because each procedure has specific advantages and disadvantages. PATIENTS AND METHODS: From June 2010 to October 2014, we performed a nephroscope-assisted "pulling-thread" technique for placement of peritoneal dialysis catheters in 46 patients with end-stage renal disease at our medical center. We retrospectively reviewed the operation-related data, early catheter-related complications during the first month after placement, and longterm technical catheter survival. RESULTS: Catheters in all 46 patients were placed precisely in a single step during surgery. The mean operative time was 63.0±18.2 minutes, and no intra-operative complications occurred in any patient. Early catheter-related complications included only exit-site infection (n=2; 4.3%) and catheter obstruction (n=2; 4.3%). There was a mean follow-up period of 18.3±12.7 months. The probability of catheter survival at 1 year was 97.1% and at 2 years was 80.1%. CONCLUSION: Our technique has the advantages of simplicity, safety, minimal equipment, low early catheter- related complication rate, and favorable long-term catheter outcome, making it ideal for patients with end-stage renal disease.

[A Case of Pyoderma Gangrenosum of the Penis Difficult to Distinguish from Fournier Gangrene].

Here, we report a case of pyoderma gangrenosum of the penis which was difficult to distinguish from Fournier gangrene. The patient was a 54-year-old male who was aware of redness and swelling of the glanspenis for 1 month prior to a consultation at our department. Although he was diagnosed with herpes and treated at a nearby hospital, his symptoms did not improve. Subsequently, the patient visited our department following the onset of pain and fever. During his initial consultation, he had a fever of 39 °C as well as redness and swelling of the glans penis with partial spontaneous purulent discharge. His blood test revealed an elevated white blood cell count (20, 000/µl) and C-reactive protein (19.1 mg/dl). Because Fournier gangrene was suspected, administration of broad-spectrum antimicrobial agents was initiated but proved to be ineffective. An abscess (2 cm in diameter) was also noted in the umbilical region.Enterococcus faecalis was detected by the bacterial culture ; and therefore, Fournier gangrene was diagnosed. A partial penectomy was performed to control the infection. Pathological findings showed only non-specific inflammation ; however, fever persisted postoperatively and blood test results showed no improvement. Furthermore, new abscess lesions emerged on the right heel and back. Because the re-performed abscess bacterial culture test result was negative, pyoderma gangrenosum was suspected, and he was started on oral prednisolone (20 mg/day). On the following day, his fever subsided and his blood test results also showed improvement. A final diagnosis of pyoderma gangrenosum was ultimately made.

[Laparoscopic excision of a retroperitoneal ganglioneuroma : a case report ].

A 32-year-old female with a history of hypertension and paroxysmal supraventricular tachycardia (PSVT) presented with a 63×39 mm, well-circumscribed retroperitoneal mass found by ultrasonography and abdominal computed tomography (CT). CT revealed a round, homogeneous tumor with calcification at the left renal hilum, and compressing the left adrenal and renal veins. Endocrinological examinations were within the normal range. Transabdominal laparoscopic excision of the retroperitoneal mass was planned because tumor malignancy could not be excluded by preoperative analyses. Histopathological examination proved that the tumor was a ganglioneuroma arising from the extra-adrenal retroperitoneum.

Re-salvage focal low-dose rate brachytherapy for local recurrence of prostate cancer after salvage focal low-dose rate brachytherapy.

Introduction: Salvage brachytherapy represents an effective treatment for local recurrence of prostate cancer after prior external beam radiotherapy. However, the optimal therapeutic strategies for local recurrence after salvage brachytherapy have not yet been determined. Case presentation: We describe the case of a 77-year-old man who underwent re-salvage focal low-dose rate brachytherapy for local recurrence after carbon ion radiotherapy and salvage focal low-dose rate brachytherapy. We performed re-salvage focal low-dose rate brachytherapy for the recurrence with a different type of seed, which resulted in a significant reduction in the prostate-specific antigen level. During the 35-month follow-up after re-salvage focal low-dose rate brachytherapy, no recurrence of prostate cancer and no severe radiation-related toxicities were observed. Conclusion: Our patient was successfully treated with re-salvage focal low-dose rate brachytherapy for local recurrence after salvage focal low-dose rate brachytherapy. This treatment strategy might be effective for such patients and is not associated with sexual dysfunction or severe adverse events.

[Pre- surgical therapy with sunitinib for adrenal metastasis from renal cell carcinoma : a case report].

A 60-year-old woman received a right radical nephrectomy for a right renal cell carcinoma (8.5×5.4 cm), cT2N0M0, in August 2000. The histopathological findings revealed a clear cell carcinoma, pT2, grade 1, INFα, v (-). She was started on interferon α (sumiferon : 300 IU) because of an adrenal metastasis from the renal cell carcinoma in August 2008. However, the tumor gradually enlarged and there was a potential to infiltrate the pancreatic body-tail. Therefore, we began the administration of sunitinib for pre-surgical therapy in June 2010, because she had a good performance status, no metastasis to other organs except for the left adrenal gland, and the passage of eight years from the time of resection of the primary origin tumor. She had a good response to therapy, which shrank the tumor by 40% (partial response). Therefore we performed a left adrenalectomy in June 2011. The histopathological findings revealed a metastatic renal cell carcinoma. We stopped the administration of after the operation sunitinib after the operation. She has since preserved her quality of life without any recurrence for 19 months.

Evaluation of sexual function after dutasteride treatment in patients with once-negative prostate biopsy and benign prostate hyperplasia.

INTRODUCTION: Patients with benign prostatic hyperplasia are usually treated with 5α-reduced inhibitors (5ARIs) such as finasteride and dutasteride. However, studies on the influence of 5ARIs on sexual function have been controversial. In this study, we evaluated the impact of dutasteride treatment for erectile function in patients with once-negative prostate biopsy and benign prostate hyperplasia. PATIENTS AND METHODS: 81 patients with benign prostate hyperplasia were enrolled in a one-armed prospective study. They were administrated 0.5 mg/day of dutasteride for 12 months. Patient characteristics and changes of International Prostate Symptom Score (IPSS) and International Index of Erectile Function (IIEF)-15 scores at baseline and 12 months after dutasteride administration were examined. RESULTS: The mean ± standard deviation (SD) age of the patients was 69.4 ± 4.9 years and the prostate volume was 56.6 ± 21.3 mL, respectively. The mean ± SD prostate volume and PSA levels were decreased 25.0 and 50.9%, respectively, after 12 months of dutasteride administration. IPSS total, voiding subscore, storage subscore, and quality of life score significantly improved after 12 months of dutasteride administration. No statistically significant change in IIEF-total score from 16.3 ± 13.5 to 18.8 ± 16.0 (p = 0.14), IIEF-EF score from 5.1 ± 6.9 to 6.4 ± 8.3 (p = 0.13) were observed. There was no decrease in erectile function severity. CONCLUSION: Twelve months administration of dutasteride for patients with BPH improved urinary function and did not increase the risk of sexual dysfunction.

[Renal salt wasting syndrome induced by Cisplatin: a case report].

A 69-year-old woman diagnosed with a urinary carcinoma was admitted to the hospital for chemotherapy consisting of cisplatin (CDDP) and gemcitabine. Two days after administration of CDDP, she complained of general fatigue. The total urine volume was 5, 500 ml/day. Three days after she received CDDP, her serum sodium level decreased to 118 mEq/l, leading to disturbed consciousness. After the intravenous administration of saline, her serum sodium levels recovered to the normal value (137 mEq/l) without any complications. The diagnosis of renal salt-wasting syndrome was made on the basis of hyponatremia, high urinary sodium excretion and increased urinary output.

[Laparoscopic renal surgery in the elderly].

It is clear that laparoscopic renal surgery has significant advantages over open renal surgery. However, current data on whether these benefits carry over to the elderly are less robust. The objective of this study was to compare the perioperative parameters of laparoscopic nephrectomy and nephroureterectomy in patients aged 70 and over versus those under 70 years of age. The new scoring system, the "E-PASS" (estimation of physiologic ability and surgical stress) was also studied. This scoring system predicts the postsurgical risk by quantifying the patient's reserve and surgical stress. E-PASS comprises the perioperative risk score (PRS), the surgical stess score (SSS), and the comprehensive risk score (CRS) that is determined using the other two scores. Between January 2006 and December 2009, a total of 55 patients who underwent laparoscopic renal surgery met the study inclusion criteria. The perioperative parameters were comparable in the younger patients and the older patients, including SSS, the postoperative complication rate, the operation time and the hospital stay. Laparoscopic renal surgery is feasible and well tolerated in elderly patients, with a low perioperative morbidity and surgical stress. Further examination on the E-PASS scoring system for application to urologic surgery was considered to be necessary. Age alone should not exclude elderly patients from definitive treatment at the outset.
