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

PURPOSE: Transurethral resection of bladder tumor (TURBT) can be a challenging procedure for an inexperienced surgeon. We suggest an easy technique for TURBT, which we have named the "grasp and bite" technique. We describe this technique and compare its effectiveness and safety with that of conventional TURBT. MATERIALS AND METHODS: Monopolar TURBT (24-Fr Karl Storz) was performed in 35 patients who had superficial bladder tumors. After defining the tumor margin, the tumor and surrounding mucosa were grasped by use of a loop electrode and resectoscope sheath. With tight grasping, linear moving resection was performed. The patients' demographic, intraoperative, and postoperative data were analyzed between the conventional and grasp and bite TURBT groups. RESULTS: Of 35 patients, 16 patients underwent conventional TURBT (group 1), and the other 19 patients underwent grasp and bite TURBT (group 2). Both groups were similar in age, tumor multiplicity, size, anesthesia method, and location. Grasp and bite TURBT could be performed as safely and effectively as conventional TURBT. There were no significant differences in irrigation duration, urethral catheterization, postoperative hemoglobin drop, or length of hospital stay. No significant side effects such as bladder perforation, severe obturator reflex, or persistent bleeding occurred. There were no significant pathological differences between specimens according to the type of resection technique. CONCLUSIONS: The grasp and bite TURBT technique was feasible for superficial bladder tumors. It may be a good tool for inexperienced surgeons owing to its convenient and easy manner.

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

INTRODUCTIONPenile cancer is an uncommon disease affecting only about one in 100,000 men worldwide in a year. The diagnosis of the condition is frequently delayed, and the disease and its treatment frequently result in significant morbidity in patients.
METHODSWe herein describe seven cases of penile tumours: six cases of squamous cell carcinomas and one case of B-cell lymphoma that presented to our hospital's urology department between March 2011 and October 2012. We reviewed the literature to discuss the clinical presentation, natural history and current management of penile cancer.
RESULTSThe patients were followed up for 1-24 months. They were managed according to their disease stage and lymph node status. Four out of seven patients showed disease progression during the follow-up period.
CONCLUSIONThe accurate staging of inguinal nodes in cases of low-risk disease is important to prescribe appropriate surgery for the inguinal nodes. Aggressive management of inguinal and pelvic lymph nodes remains the cornerstone in the treatment of high-risk disease cases.

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

OBJECTIVETo study the clinical and pathologic characteristics of small cell neuroendocrine carcinoma of urinary tract.
METHODSAll cases of urinary tract carcinoma encountered in the General Hospital of People Liberation Army during the period from 1999 to 2010 were retrospectively reviewed. The clinicopathologic data of small cell neuroendocrine carcinomas were further analyzed, with literature review.
RESULTSA total of 16 cases of small cell neuroendocrine carcinoma were identified, including 10 from urinary bladder, 2 from ureter, 3 from renal pelvis, and 1 multifocal tumor involving renal pelvis and ureter. There were altogether 8 males and 8 females. The median age of the patients was 63 years (range = 24 to 79 years). Gross hematuria (11 cases) represented the main presenting symptom. Four patients had flank pain and 4 had urinary irritation symptoms. Seven patients underwent radical cystectomy. Six other patients underwent radical nephroureterectomy, 1 partial cystectomy, 1 TURBT and the remaining case biopsy only. The size of the tumor ranged from 0.8 to 8.0 cm (median = 4.5 cm). Histologically, 15 cases represented mixed small cell neuroendocrine carcinoma (with 13 mixed with transitional cell carcinoma and 2 with adenocarcinoma). Immunohistochemical study showed positive staining for neuroendocrine markers. On presentation, 1 patient was in stage pT1, 7 in stage pT2, 6 in stage pT3, 2 in stage pT4. Six patients died of the disease after operation. The overall survival was 25 months and the 5-year survival rate was 32.4%.
CONCLUSIONSSmall cell neuroendocrine carcinoma of urinary bladder is a highly malignant disease and associated with poor prognosis. The diagnosis relies on detailed histologic examination. Early diagnosis, when coupled with cystectomy or nephroureterectomy and adjuvant chemotherapy, represents the mainstay of management.

OBJECTIVE: To determine the validity of NMP-22 (Bladder Check Protein Test Pack Kit) in the diagnosis of bladder cancer.
MATERIALS: From May 1, 2009 to October 31, 2009 all patients with bladder mass by ultrasound, IVP or CT scan from three different urology training institutions were enrolled in this prospective study. These patients underwent urine cytology and NMP-22 qualitative assay. The diagnosis determined from the cytoscopic and histopathologic findings from CTURBT was accepted as the gold standard.
RESULTS: Thirty nine subjects were enrolled in this study, whom of 31 patients were diagnosed of malignancy and 8 were benign in pathology. The sensitivity of urine cytology, NMP-22 assay and cytoscopy was 34.6%, 96.8% and 92.3% respectively and the specificity was 37.5% for NMP-22 and 66.1% for the cytoscopy.
CONCLUSION: The result of this study suggests that NMP-22 is a very sensitive test, however is less specific in identifying bladder cancer.
