Super extended versus extended pelvic lymph node dissection in patients undergoing radical cystectomy for bladder cancer: a comparative study

There is evidence from retrospective studies that radical cystectomy with extended pelvic lymph node dissection provides better staging and outcomes than limited lymph node dissection. However, the optimal limits of extended lymph node dissection remain unclear. We compared oncological outcomes at 2 cystectomy centers where 2 different extended lymph node dissection templates are practiced to determine whether removing lymphatic tissue up to the inferior mesenteric artery confers an additional survival advantage.

Irrigation of continent catheterizable ileal pouches: tap water can replace sterile solutions because it is safe, easy, and economical

Continent catheterizable ileal pouches require regular irrigations to reduce the risk of bacteriuria and urinary tract infections (UTIs).

Lymphadenectomy for bladder cancer: indications and controversies

Pelvic lymph node dissection (PLND) at the time of cystectomy remains the most accurate method of staging and can have a positive impact on cancer control, and there is general agreement as to its necessity at the time of surgery. There is, however, a lack of consensus regarding the terminology of PLND and controversy concerning the optimal extent of lymph node dissection, especially because recent investigations have suggested a survival benefit with extended PLND.

Long-term renal function after urinary diversion by ileal conduit or orthotopic ileal bladder substitution

Data on long-term renal function are scarce for ileal conduit diversion (ICD) and even rarer for orthotopic ileal bladder substitution (BS).

Acid-sensing channels in human bladder: expression, function and alterations during bladder pain syndrome

We examined the possible role of H(+) activated acid-sensing ion channels in pain perception. We characterized expression in bladder dome biopsies from patients with bladder pain syndrome and controls, in cultured human urothelium and in urothelial TEU-2 cells.

Structural differences between the bladder dome and trigone revealed by mRNA expression analysis of cold-cut biopsies

To establish the mRNA expression profiles of selected genes involved in bladder contractility and epithelial permeability in the bladder dome and trigone in order to evaluate the use of cold-cut biopsies for comparative quantitative studies into the anatomical differences between these two bladder regions.

Extended lymph node dissection: bladder, kidney

To present recent advances in the field of lymph node dissection (LND) in the context of bladder cancer, upper urinary tract urothelial carcinoma and renal cell carcinoma with focus on dissection extent.

Urothelial neoplasms of the urinary bladder occurring in young adult and pediatric patients: a comprehensive review of literature with implications for patient management

Bladder urothelial carcinoma is typically a disease of older individuals and rarely occurs below the age of 40 years. There is debate and uncertainty in the literature regarding the clinicopathologic characteristics of bladder urothelial neoplasms in younger patients compared with older patients, although no consistent age criteria have been used to define "younger" age group categories. Use of the World Health Organization 2004/International Society of Urological Pathology 1998 grading nomenclature and recent molecular studies highlight certain unique features of bladder urothelial neoplasms in young patients, particularly in patients below 20 years of age. In this meta-analysis and review, the clinical, pathologic, and molecular features and risk factors of bladder urothelial neoplasms in patients 40 years or less are presented and analyzed according to decades of presentation. Similar to older patients, bladder urothelial neoplasms in patients 40 years or younger occur more common in male patients, present mainly with gross painless hematuria, and are more commonly located at bladder trigone/ureteral orifices, but in contrast have a greater chance for unifocality. Delay in diagnosis of bladder urothelial neoplasms seems not to be uncommon in younger patients probably because of its relative rarity and the predominance of benign causes of hematuria in this age group causing hesitancy for an aggressive work-up. Most tumors in patients younger than 40 years were low grade. The incidence of low-grade tumors was the lowest in the first 2 decades of life, with incremental increase of the percentage of high-grade tumors with increasing age decades. Classification according to the World Health Organization 2004/International Society of Urological Pathology grading system identified papillary urothelial neoplasms of low malignant potential to be relatively frequent among bladder tumors of young patients particularly in the teenage years. Similar to grade, there was marked predominance of low stage tumors in the first 2 decades of life with gradual inclusion of few higher stage and metastatic tumors in the 2 older decades. Bladder urothelial neoplasms occurring in patients <20 years of age lack or have a much lower incidence of aberrations in chromosome 9, FGFR3, p53, and microsatellite instability and have fewer epigenetic alterations. Tumor recurrence and deaths were infrequent in the first 2 decades and increased gradually in each successive decade, likely influenced by the increased proportion of higher grade and higher stage tumors. Our review of the literature shows that urothelial neoplasms of the bladder occurring in young patients exhibit unique pathologic and molecular features that translate to its more indolent behavior; this distinction is most pronounced in patients <20 years. Our overall inferences have potential implications for choosing appropriate noninvasive diagnostic and surveillance modalities, whenever feasible, and for selecting suitable treatment strategies that factor in quality of life issues vital to younger patients.

Painful bladder syndrome: management and effect on sexual function and quality of life

Primary aim of this study was to evaluate the effect of our therapeutical management in patients with painful bladder syndrome (PBS)/interstitial cystitis (IC) on sexual function, quality of life and bladder symptoms using validated tools prospectively

Potential and limitations of diffusion-weighted magnetic resonance imaging in kidney, prostate, and bladder cancer including pelvic lymph node staging: a critical analysis of the literature

Diagnosis, staging, and treatment monitoring are still suboptimal for most genitourinary tumours. Diffusion-weighted magnetic resonance imaging (DW-MRI) has already shown promise as a noninvasive imaging modality in the early detection of microstructural and functional changes in several pathologies of various organs.

Aseptic tissue necrosis and chronic inflammation after irrigation of penetrating hand wounds using Octenisept®

Penetrating hand wounds are common and these are managed by thorough debridement. However, stab wounds without evidence of divided structures are often treated with irrigation using antiseptic substances, antibiotic therapy, and immobilization. Octenisept® (Schülke & Mayr Ltd) is a widely used antiseptic agent for disinfection of acute or chronic wounds. It has a broad spectrum of antiseptic efficacy and has become an antiseptic of first choice in many hospitals. Within a few months, four patients presented to us with chronic inflammation and severe tissue necrosis after irrigation of penetrating hand wounds with Octenisept®. Repeated surgery and debridement was required in all patients. Wound healing was prolonged and patients had persisting oedema. Penetrating hand wounds must not be irrigated with Octenisept®.

Clinical and microbiologic results 12 months after scaling and root planing with different irrigation solutions in patients with moderate chronic periodontitis: a pilot randomized trial

The aim of this study is to determine in a randomized trial the impact on treatment outcome after 12 months of different subgingival irrigation solutions during scaling and root planing (SRP).

Ultrasmall superparamagnetic particles of iron oxide allow for the detection of metastases in normal sized pelvic lymph nodes of patients with bladder and/or prostate cancer

Lymph node metastases influence prognosis and outcome in patients with bladder and prostate cancer. Cross sectional imaging criteria are limited in detecting metastases in normal sized lymph nodes. This prospective study assessed the diagnostic accuracy of ultrasmall superparamagnetic particles of iron oxide (USPIO)-enhanced magnetic resonance imaging (MRI) for the detection of metastases in normal sized lymph nodes using extended pelvic lymph node dissection (ePLND) and histopathology as the reference standard.
