Interpretation of next-generation sequencing (NGS) of tumor tissue in patients with advanced Urinary Tract Cancer (UTC) is performed to guide treatment selection but may reveal pathogenic variants with germline implications. We identified three patients with UTC with unexpected germline DNA repair gene mutations. Specific testing for these was prompted by the detection of these mutations by tumor NGS. All three patients were nonsmokers with a strong family history of cancer. Two patients had upper tract UTC with age at diagnosis in the 40 s...

A drug-eluting biodegradable ureteral stent (BUS) has been developed as a new approach for the treatment of urothelial tumors of upper urinary tract cancer. In a previous work, this system has proven to be a good carrier for anticancer drugs as a potential effective and sustainable intravesical drug delivery (IDD) system. BUS has revealed to reduce in 75% the viability of human urothelial cancer cells (T24) after 72 h of contact and demonstrated minimal cytotoxic effect on human umbilical vein endothelial cells (HUVECs) which were used as a control...

INTRODUCTION: The so-called stent-related symptoms caused mainly by detrusor overactivity due to distal ("cystic") curl of the internal stent are common among patients with this type of drainage. The need for long-term stenting makes the quality of life of cancer patients one of the challenging problems of modern urology. The aim of this study was to optimize treatment of stent-related symptoms in cancer patients with internal long-term stents by complementing the treatment regimen with m-anticholinergic solifenacin...

There is conflicting evidence on the impact of urolithiasis on the risk of developing cancer of kidney and upper urinary tract. Most researchers are of the opinion that there is a definite association between the diseases and clinicians should take the necessary measures to detect possible malignancy of the kidney and upper urinary tract in patients with urolithiasis at the earliest stages. However, the pathophysiological mechanisms that may underlie the development of renal cell carcinoma and urothelial cancer in patients with urolithiasis remain unexplored...

Non-transitional cell carcinomas (non-TCC) of the upper urinary tract as squamous cell carcinoma (SCC), adenocarcinoma, and small cell carcinoma (SmCC) are rare with few case reports in the literature. We retrospectively reviewed our patients who surgically treated for upper tract urothelial carcinoma from 1983 to 2013 for non-TCC pathological cancer characteristics and survival. Among 305 patients, only 5 (1.6%) cases were found: One case of SmCC, another had adenocarcinoma, and 3 SCC cases. None of them had intravesical recurrence and the cancer-specific survival for non-TCC cohort is markedly decreased (log-rank = 0...

Rectovaginal fistula (RVF) and vesicovaginal fistula (VVF) are infrequent but distressing complications after pelvic surgery. However, their adequate treatment is not well described. Here, we simultaneously encountered and successfully treated RVF and VVF after radical surgery for rectal cancer. A 70-year-old woman underwent low anterior resection (LAR) combined with resection of the uterus, the bilateral adnexa, and the upper side of the vagina, as well as diverted ileostomy for rectal cancer. A month after the surgery, she developed urinary incontinence and underwent medical treatment, but her symptoms did not improve...

This protocol describes the generation of bladder tumors in female C57BL/6J mice using the murine bladder cancer cell line MB49, which has been modified to secrete human Prostate Specific Antigen (PSA), and the procedure for the confirmation of tumor implantation. In brief, mice are anesthetized using injectable drugs and are made to lay in the dorsal position. Urine is vacated from the bladder and 50 µL of poly-L-lysine (PLL) is slowly instilled at a rate of 10 µL/20 s using a 24 G IV catheter. It is left in the bladder for 20 min by stoppering the catheter...

BACKGROUND: A urethral stricture is a scar of the urethral epithelium which can cause obstructive voiding dysfunction with consequential damage of the upper urinary tract. Almost 45% of all strictures are iatrogenic; they develop in 2-9% of patients after radical prostatectomy, but can also occur after prostate cancer radiotherapy. This study provides 5‑year data of a certified prostate cancer center (PKZ) in terms of urethral strictures. MATERIALS AND METHODS: Between 01/2008 and 12/2012 a total of 519 men were irradiated for prostate cancer (LDR and HDR brachytherapy as well as external beam radiation)...

Lymph node dissection represents an essential surgical step in the treatment of the most commonly treated urological cancers. The introduction of robotic surgery has lead to the possibility of treating these diseases with a minimally invasive surgical approach, but the surgical principles of open surgery need to be carefully respected in order to achieve comparable oncological results. Therefore, the robotic approach to urological cancers must include a carefully performed lymph node dissection when indicated...
