OBJECTIVE To describe our en-bloc technique of retroperitoneal lymph node dissection (RPLND) during retroperitoneal laparoscopic radical nephroureterectomy (RNU) for upper urinary tract urothelial carcinoma (UTUC) and evaluate perioperative outcomes. METHODS From 2002 to 2015, 114 patients with UTUC located at the pelvis and/or upper or middle ureter underwent retroperitoneal laparoscopic RNU at two institutions. Performance of RPLND began in February 2009. The template of RPLND included the renal hilar and para-aortic lymph nodes (left side) and the renal hilar, paracaval, retrocaval, and intra-aortocaval lymph nodes (right side)...

CONTEXT: The oncological efficacy of routine lymphadenectomy (lymph node dissection [LND]) at the time of radical nephroureterectomy (RNU) remains controversial. OBJECTIVE: To systematically review the available literature assessing the impact of LND in upper tract urothelial carcinoma (UTUC) patients. EVIDENCE ACQUISITION: Embase, Medline, and Cochrane databases were searched for all studies comparing outcomes of patients undergoing RNU without LND versus any form of LND...

L-shaped kidney refers to a rare anomaly of the relative kidney positioning. Due to low prevalence, the literature on the co-occurrence of this anomaly with malignancy is lacking. And, if the diagnosis of a renal anomaly does not present difficulties, if a tumor is detected in such a kidney, even MSCT does not always help differentiate a pelvic tumor from a tumor of the renal parenchyma spreading to the pelvicalyceal system. This has important implications for choosing an appropriate surgical strategy. A feature of the presented clinical observation is the co-occurrence of the rare anomaly of kidney position and locally advanced renal cell carcinoma spreading to the renal pelvis...

AIMS: To further characterize biphasic squamoid renal cell carcinoma (RCC), a recently proposed variant of papillary RCC. METHODS AND RESULTS: We identified 28 tumors from multiple institutions. They typically demonstrated two cell populations - larger cells with eosinophilic cytoplasm and higher-grade nuclei, surrounded by smaller, amphophilic cells with scanty cytoplasm. The dual morphology was variable (median 72.5% of tumor, range 5-100%); emperipolesis was found in all cases...

A 60-year-old man had a past history of urothelial carcinoma of the left renal pelvis treated with laparoscopic left total nephroureterectomy in October 2004. He underwent transurethral resection of the bladder tumor (TUR-Bt) twice for recurrence of urothelial carcinoma in the bladder in April 2014 and February 2015, and subsequently received intravesical Bacillus Calmette-Guerin (BCG) instillation at weekly intervalsfor prevention of recurrence. In November 2016, a year and a half after BCG induction, he received BCG therapy after urethral bougie to dilate the urethral stricture...

Although the second most common malignancy after urothelial carcinoma, squamous cell carcinoma (SCC) of the renal pelvis is a rare entity. It has strong association with nephrolithiasis thus emphasizing prompt treatment of renal calculi. Because of rarity and nonspecific clinical and radiological findings, it mostly presents at pT3 or higher stage. We report SCC of renal pelvis that was missed two times on non-contrast CT scans and was diagnosed incidentally in a nephrectomy specimen. Its prognosis is similar to that of urothelial carcinoma of comparable stage...

An 83-year-old Japanese man had a history of chronic heart failure due to bradycardia-tachycardia syndrome. He was admitted to our hospital because of macrohematuria and acute kidney injury (AKI), which were detected by an urologist at an outpatient visit. He had a history of recurrent macrohematuria and transurethral resection of bladder tumors twice in the preceding 2 years. He had been on warfarin for 12 years, with a stable international normalized ratio (INR) that was usually less than 2.1. Urinalysis revealed numerous red blood cells (RBCs) and mild proteinuria without RBC casts...

BACKGROUND: Metastatic urothelial carcinoma of the bladder, ureter, or renal pelvis is a highly aggressive disease with poor outcomes. Even with platinum-based chemotherapy, the median overall survival is 15 months and the 5-year survival is only 15%. The role of metastasectomy in urothelial carcinoma is currently undefined. OBJECTIVE: To examine the use and outcomes of metastasectomy in older patients with urothelial carcinoma in a large population-based dataset...

PURPOSE: Tumor genomic profiling helps direct therapy for advanced urothelial carcinoma (UC). In the course of clinical care, we encountered a patient with a complete loss of SMARCB1 (switch/sucrose nonfermentable-related matrix-associated actin-dependent regulator of chromatin subfamily B member 1), which encodes INI-1 (integrase interactor 1), as the sole detected driver of their urinary tract tumor. Our objective was the identification and genomic characterization of urinary tract neoplasia with complete SMARCB1 loss...

According to WHO classification system, non-invasive urothelial carcinoma represents urothelial carcinoma in situ (CIS) and dysplasia. Dysplastic urothelium often progresses to CIS that further advances to urothelial carcinoma (UC). The strongest risk factor for UC is cigarette smoking. However, the pathogenesis of cigarette smoke (CS)-induced UC is poorly understood. Earlier we had shown that p-benzoquinone (p-BQ), a major toxic quinone derived from p-benzosemiquinone of CS in vivo, is a causative factor for various CS-induced diseases...

Renal cell carcinoma (RCC) is the most common malignancy that results in venous tumor thrombosis. Transitional cell carcinoma of the renal pelvis with renal or vena cava thrombus is extremely rare. Fewer than 40 cases have been reported. We report a similar case of a patient who underwent radical nephrectomy with a preoperative diagnosis of RCC.

BACKGROUND: Kidney transplantation (KT) is the treatment option for patients with end stage renal disease (ESRD) to prolong survival and improve quality of life. Although the use of potent immunosuppressive agents increases graft survival in kidney transplantation recipients (KTRs), it may lead to the development of malignancy, including transitional cell carcinoma (TCC). TCC developing in the pelvis of graft kidney is very rare in KTRs. CASE PRESENTATION: A 40-year-old male visited hospital with complaints of nausea, vomiting and gross hematuria...

BACKGROUND: The aim of this study was to revise the histopathologic types of neoplasias in the genitourinary tract and determine the frequency of 2 new entities included in the 2016 book of World Health Organization classification of renal tumors. It is not established so far whether these 2 recently described tumors are the most frequent in association with end-stage kidney disease. METHODS: In a retrospective analysis, we revised the histopathologic type of 37 genitourinary tumors from 21 patients in dialysis and/or submitted to renal transplantation from 2003 to 2016 aiming to find the frequency of acquired cystic disease-associated renal cell carcinoma and clear cell papillary (tubulopapillary) renal cell carcinoma...

A 47-year-old male presented with haematuria and flank pain for two weeks. Ultrasonography and renal scan revealed a poorly functioning left kidney with multiple calculi. Simple nephrectomy was performed and the specimen revealed a mass in his renal pelvis which showed both carcinomatous and sarcomatous components on microscopy. The sarcomatous component consisted of diffuse pleomorphic osteoblasts with intervening lacy osteoid, giving an osteosarcoma-like appearance. These areas of tumour were strongly positive for vimentin and osteopontin...
