AIMS: Sorafenib, which has been used extensively for the treatment of renal cell cancer and advanced hepatocellular carcinoma (HCC), has also been shown to have antifibrotic effects in liver fibrosis. However, the effects of sorafenib on renal fibrosis are unknown. Therefore, we investigated whether sorafenib inhibited renal fibrosis in a mouse model of unilateral ureteral obstruction (UUO) and further explored the potential mechanism. METHODS: Mice underwent UUO followed by vehicle or sorafenib treatment...

PURPOSE: Cancerous involvement of a ureter is sometimes encountered in pelvic surgery for malignancy. We usually perform transureteroureterostomy (TUU) in cases of unilateral lower ureteral cancerous involvement. We report the outcomes in patients treated with TUU in our institute. METHODS: We retrospectively reviewed the medical records of 11 patients who underwent TUU between June 2006 and September 2015. RESULTS: The primary disease was colon cancer in five patients, rectal cancer in four, and uterine cervical cancer and ovarian cancer in one patient each...

Ureteral urothelial carcinoma (UC) is a rare malignant tumor. The most common clinical manifestations of ureteral UC are hematuria, increased urinary frequency, dysuria and pain. The diagnosis of ureteral UC is made via radiography, endoscopy and pathology. Although osteoblastic destruction is usually observed in metastasis of prostate cancer, UC can also be a reason for osteoblastic metastasis. The present study reports the case of a 66-year-old man presenting with osteoblastic metastases, in which the primary tumor was finally diagnosed as a ureteral UC...

Galectins are evolutionary conserved β-galactoside binding proteins with a carbohydrate-recognition domain (CRD) of approximately 130 amino acids. In mammals, 15 members of the galectin family have been identified and classified into three subtypes according to CRD organization: prototype, tandem repeat-type and chimera-type galectins. Galectin-3 (gal-3) is the only chimera type galectin in vertebrates containing one CRD linked to an unusual long N-terminal domain which displays non-lectin dependent activities...

PURPOSE: Ureteral obstruction in cervical cancer occurs in up to 11% of patients, many of whom undergo ureteral stenting. Our aim was to describe the patient burden of chronic ureteral stenting in a population-based cohort by detailing two objectives: (1) the frequency of repeat procedures for ureteral obstruction; and, (2) the frequency of urinary adverse effects (UAEs) (e.g., lower urinary tract symptoms, flank pain). MATERIALS AND METHODS: From SEER-Medicare, we identified 202 women who underwent ureteral stent placement prior to or following cervical cancer treatment...

BACKGROUND: Prostate cancer is the most commonly diagnosed cancer in men in Nigeria and most cases present when the disease is already in an advanced stage. Radical prostatectomy for early prostate cancer is therefore not a commonly performed operation by urologists in Nigeria. We have had training and significant experience in radical retropubic prostatectomy. We, therefore, report the outcome of our initial experience. MATERIALS AND METHODS: We review the record of men with early prostate cancer who had radical retropubic prostatectomy in our institution from 2007 to 2015...

Bladder exstrophy is a rare malformation. Ureteral diversion, such as ureterosigmoidostomy or a neorectal bladder, has been described. When the patients reach adulthood, cancer may arise in these reconstructions. Our aim was to perform a systematic review (all languages) of the published literature on neoplasia after urinary diversion and suggested management in cases of cancer. PubMed and Cochrane library were searched for relevant articles published within the last 20 years. All identified articles were reviewed for inclusion...

Upper urinary tract urothelial carcinoma (UTUC) accounts for 5-10% of urothelial carcinomas and is a disease that has not been widely studied as carcinoma of the bladder. To avoid the problems of conventional therapies, such as the need for frequent drug instillation due to poor drug retention, we developed a biodegradable ureteral stent (BUS) impregnated by supercritical fluid CO2 (scCO2) with the most commonly used anti-cancer drugs, namely paclitaxel, epirubicin, doxorubicin, and gemcitabine. The release kinetics of anti-cancer therapeutics from drug-eluting stents was measured in artificial urine solution (AUS)...

We highlight two cases of transperitoneal robot-assisted radical prostatectomy (RARP) in patients with pelvic kidneys because of congenital development and renal transplant. These uncommon cases present a challenge to the surgeon contemplating surgery because of access and anomalous vascular and ureteral anatomy. We describe the technical considerations that are paramount in effectively completing transperitoneal RARP, and believe it should be considered as a treatment option in men with pelvic kidneys.

A 79-year-old woman with a history of diabetes mellitus and recurrent urinary tract infections (UTIs) presented with acute onset left lower quadrant pain, left-sided back pain, vomiting, and dysuria. Abdominopelvic CT scan revealed left hydroureteronephrosis to the level of the left ureterovesical junction (UVJ) where a bladder mass appeared to be obstructing the left ureteral orifice. The obstruction was ultimately found to be the result of a sloughed renal papilla lodged in the distal ureter, which created an inflammatory mass at the UVJ...

To explore the clinical pathological characteristics and improve the recognition in the diagnosis and treatment of basal cell carcinoma (BCC) of prostate. Three cases of BCC of prostate were reported and the relevant literature was reviewed to investigate the diagnosis and treatment of this disease. We analyzed three cases of prostatic BCC. Their ages were within a range of 57 to 83 years. One of them complained of hematuria and two complained of dysuria. All of them presented with prostatic hyperplasia. Two of them presented with high prostate specific antigen (PSA) and one with normal PSA...

OBJECTIVE: To describe the management of grade 4 Radiation Therapy Oncology Group (RTOG) urinary adverse events (UAEs) after radiotherapy (RT) for prostate cancer (PCa). We hypothesized grade 4 UAEs often require complex surgical management and subject patients to significant morbidity. METHODS: A single-center retrospective review, over a 6-year period (2010-2015), identified men with RTOG grade 4 UAEs after RT for PCa. RT was classified as combined modality therapy (radical prostatectomy (RP) followed by external beam radiotherapy (EBRT), EBRT + low-dose brachytherapy (LDR), EBRT + high-dose brachytherapy (HDR), or other combinations of RT) or single modality RT...

Abdominal wall metastasis from urothelial cancer is extremely rare and very few such cases have been reported in the literature. As such the treatment protocols are not so well defined. We present an interesting case of a 65-year-old male patient, known case of chronic kidney disease, who presented with a large, fungating infraumbilical mass 8 months postradical cystectomy. The mass involved full thickness anterior abdominal wall and small bowel including the ileal conduit. Wide excision of the mass along with adhered bowel loops and partial excision of the ileal conduit with right ureteric reimplant was performed...

BACKGROUND: Our previous nonrandomized prospective study showed that template-based lymphadenectomy improved survival among patients with renal pelvic cancer but not among patients with ureteral cancer. However, regional node sites vary according to the tumor's location in relation to the ureter. Therefore, this retrospective study examined the therapeutic role of lymphadenectomy for ureteral cancer according to tumor location. METHODS: Between January 1988 and September 2015, we performed nephroureterectomy for 154 patients with nonmetastatic urothelial carcinoma of the ureter at two Japanese institutions...
