Introduction: Studies comparing refluxing versus non-refluxing ureteric implantation in continent cutaneous urinary diversion (CCUD) are scarce and often characterized by heterogeneous study populations. This work therefore aimed at comparing both techniques regarding long-term outcomes in a propensity-scored approach.
Methods: We identified n = 19 patients, totaling n = 38 renal units (RU), who underwent CCUD surgery at our hospital out of a pool of 120 patients.
Objectives: To provide a detailed step-by-step operative technique, and to report on long-term functional and metabolic outcomes in secondary continence mechanisms in the form of secondary intussuscepted ileal nipple valves in revisional surgery of ileocecal pouches.
Methods: From May 1997 to May 2015, 18 female and 10 male patients suffering from dysfunctional primary continence mechanisms of their ileocecal pouch underwent revisonal surgery to create a secondary ileal nipple valve at our tertiary referral center. The average follow-up period was 65.
Background: Despite latest advances in prostate cancer (PCa) therapy, PCa remains the third-leading cause of cancer-related death in European men. Dysregulation of microRNAs (miRNAs), small non-coding RNA molecules with gene expression regulatory function, has been reported in all types of epithelial and haematological cancers. In particular, miR-221-5p alterations have been reported in PCa.

Patients And Methods: A total of 106 patients (n = 26 ileal conduits, n = 29 neobladders, and n = 51 ileocecal pouches) were included in this combined retrospective (n = 77) and prospective (n = 29) observational study. All patients performed the 2 tests mentioned above and filled out self-designed questionnaires with diversion and HRQoL items.
Background: Mucinous tubular and spindle cell carcinoma (MTSCC) is a rare type of renal cell carcinoma, whose clinical behaviour and metastatic potential have not been fully elucidated to date. There are only a few metastatic cases in the literature, which all either featured sarcomatoid differentiation or were synchronously metastasised at diagnosis.
Case Presentation: We report a case of a 49-year-old male with end-stage kidney disease on dialysis, presenting with multiple osseous metastases of a mucin-poor variant of MTSCC of the kidney, without sarcomatoid differentiation, two years after bilateral nephrectomy for papillary renal cell carcinoma (RCC) at a curable stage.
Saphenous vein graft (SVG) aneurysms (SVGA) after renal transplantation represents a rare vascular complication with subsequent challenging multidisciplinary treatment. We present a case of a 30-year-old female who received a live donor kidney transplantation for end-stage renal disease that was caused due to the hemolytic uremic syndrome. Postoperatively, an insufficient graft perfusion due to an arterial kinking was noted and repaired using an autologous SVG interposition.

Patients And Methods: From 2015 to 2017, six patients with unreconstructable, incontinent outlets (out of a total pool of 595 patients with CCUD) have undergone the technique described in the present paper at our department. The technique relies on the Mitrofanoff principle, using a stapled full-thickness pouch wall plication, which creates a flap-valve continence mechanism.
Purpose: To validate preoperative C-reactive protein (CRP) levels as a prognostic marker for survival in a metastasized renal cell carcinoma (mRCC) patient cohort receiving cytoreductive nephrectomy (CN).
Patients And Methods: By chart review, 146 mRCC patients receiving CN at our tertiary referral centre from 1997 to 2015 were identified retrospectively. All relevant clinicopathological features including laboratory parameters were collected and correlated to overall survival, progression-free survival and cancer-specific survival (CSS).
Objective: To report the long-term outcomes of ileal ureteric replacement (IUR) in complex reconstruction of the urinary tract.
Patients And Methods: From 1991 to 2016, IUR was performed in 157 patients with structural or functional ureteric loss. In 52 patients, bilateral IUR became necessary.
Background: Radiotherapy plays a substantial role in the treatment of malignancies. More than 2/3 of all oncologic patients undergo radiotherapy during their specific treatment. Besides manifold side effects of radiotherapy, radiogenic fistulas of the urogenital tract are a potential severe complication.

Patients And Methods: Five male patients aged 48-89 were referred to our department between 2000 and 2016 with a ruptured ileocecal pouch 16-175 months postoperatively.
Results: With an incidence of 0.
Purpose: We investigated the long-term oncological and functional outcome of nephron-sparing surgery/partial nephrectomy (PN) versus radical nephrectomy (RN) for any renal cell carcinoma (RCC) ≥4 cm.
Patients And Methods: Between 1997 and 2013, we identified 128 patients undergoing PN for RCC ≥4 cm and matched this collective to 128 patients undergoing RN. We then compared overall survival (OS), cancer-specific survival (CSS), progression-free survival (PFS) and functional parameters in both groups.
The role of maintenance therapy with Gemcitabine (GEM) following cisplatin-based combination chemotherapy (CBCC) in patients with surgically treated advanced urothelial carcinoma (UC) remains to be fully elucidated. In the present case control study, a retrospective analysis was performed to evaluate the role of GEM monotherapy following surgical intervention for advanced UC. Between 1999 and 2013, 38 patients were identified with surgically treated advanced UC after having completed CBCC, who were additionally treated quarterly with two consecutive GEM (1,250 mg/m) infusions as maintenance therapy.

Patients And Methods: One hundred thirty-nine consecutive patients with biochemical recurrence after curative (surgery and/or radiotherapy) therapy were offered participation in this sequential clinical imaging approach. Patients first underwent an F-choline-PET/CT.
Background: Radiotherapy plays a substantial role in the treatment of malignancies. The side effects and long-term sequelae of radiotherapy are manifold and depend on the single doses and the total dosage, the time interval between two doses, the size of the irradiated tissue area and the radiation sensitivity of individual tissues. The urological complications following radiotherapy include inflammatory alterations of the bladder (radiation-induced hemorrhagic cystitis), fibrosis with subsequent radiogenic shrunken bladder, stenosis of the ureter and formation of secondary retroperitoneal fibrosis.

Methods: Proliferation assays (MTS) and qRT-PCR after transient transfection with pre- and anti-miR-21 and MF treatment were conducted.
Purpose Of Review: The purpose of this study is to review and discuss recently published studies of therapeutic options in cases with the combination of severe sphincteric damage and recurrent stricture of the bladder neck or anastomosis in patients with postradical prostatectomy.
Recent Findings: Recent focus has been on successful management of recurrent bladder neck contracture with urethral dilatation or endoscopic techniques even in patients with prior history of additional radiation therapy. In addition, some authors include injectable agents in their armamentarium for the treatment of recurrent bladder neck stricture.
Unlabelled: Prostate-specific membrane antigen (PSMA) is a promising target for diagnosis and treatment of prostate cancer. EuK-Subkff-(68)Ga-DOTAGA ((68)Ga-PSMA Imaging & Therapy [PSMA I&T]) is a recently introduced PET tracer for imaging PSMA expression in vivo. Whole-body distribution and radiation dosimetry of this new probe were evaluated.

Methods: A combinatorial random peptide library was screened on the circulating pool of immunoglobulins purified from an index patient with a high risk TCC (pTa high grade plus carcinoma in situ) to identify corresponding target antigens. A patient cohort was investigated for antibody titers against ubiquitin.
Purpose: Living kidney donation (LKD) involves little risk for the donor and provides excellent functional outcome for transplant recipients. However, contradictory data exist on the incidence and degree of impaired renal function (IRF) in the donor. Only few studies compared the incidence of IRF in donors with that of patients having undergone radical nephrectomy (RN).

Nevertheless, the risk for tumor recurrence after nephrectomy and thrombectomy varies. An applicable and accurate prediction system to select ccRCC patients with TT of the IVC (ccRCC/TT) at high risk after nephrectomy is urgently needed, but has not been established up to now.

View Article and Find Full Text PDFA lack of reliably informative biomarkers to distinguish indolent and lethal prostate cancer is one reason this disease is overtreated. miR-221 has been suggested as a biomarker in high-risk prostate cancer, but there is insufficient evidence of its potential utility. Here we report that miR-221 is an independent predictor for cancer-related death, extending and validating earlier findings.
