Background: Urine examination has relevance for treatment, and reliability of positive urine culture (UC) is of importance. The technique of urine sampling (US), storage, and transportation is important. The objective of this study was to investigate if detailed patient information for the technique of US and hygiene reduces rates of contaminated UC in screened male patients, as this group was not investigated yet.

Article Synopsis
  • TTNS (Transcutaneous Tibial Nerve Stimulation) is an effective treatment for lower urinary tract conditions, showing significant improvements in bladder function compared to a placebo.
  • In a study with 51 patients, TTNS resulted in a notable increase in filling volume at first desire to void and maximum cystometric capacity, particularly benefiting those without anatomical pathologies.
  • While TTNS had positive effects on bladder functioning, patients with anatomical issues did not experience improvements, indicating a need for further research on the effectiveness of bilateral vs. unilateral TTNS.

Article Synopsis
  • The study aimed to evaluate the effectiveness of epidermal vacuum wound dressings compared to conventional wound care in patients undergoing inguinal lymphadenectomy for penile cancer.
  • A total of 31 patients were involved, with results showing no significant differences in fluid drainage, complication rates, or hospital stays between the two treatment methods.
  • The findings suggest that both approaches yield similar outcomes, indicating that the vacuum dressing may not provide additional benefits over conventional methods in this patient population.

Background: Recently, antibiotic resistance rates have risen substantially and care for patients infected with multidrug-resistant organisms (MDRO) has become a common problem in most in - and outpatient settings. The objectives of the study were to compare the awareness, perception, and knowledge of MDRO and rational antibiotic use between physicians from different medical specialties in German hospitals.

Methods: A 35-item questionnaire was sent to specialists in internal medicine (internists), gynecologists, urologists, and general surgeons (non-internists) in 18 German hospitals.

Objectives: To assess the rate of urinary tract infection (UTI), the characteristics of the bacterial aetiological agents involved, the type and duration of antibiotics used, and the clinical risk factors of UTI in a multi-institutional cohort of patients who had undergone radical cystectomy (RC).

Patients And Methods: The pre- and postoperative characteristics of patients who had undergone open RC at 1 of 3 institutions between 2009 and 2015 were analyzed by means of the patient charts. Patients were classified according to the presence or absence of UTI.

Purpose: To compare the oncological long-term efficacy of whole gland high-intensity focused ultrasound (HIFU) therapy and radical prostatectomy (RP) in patients with clinically localized prostate cancer.

Methods: 418 patients after open RP (1997-2004) were compared with 469 patients after whole gland HIFU (1997-2009) without preselection. Oncological follow-up focused on biochemical relapse, salvage treatment, life status and cause-specific mortality.

Purpose: Our objective was to investigate whether patients with urologic tumors were aware of smoking as a risk factor for the development and progression of several urologic cancers and the extent of the medical education they had received. Another aim was to investigate whether gender or age influenced patients' willingness to change their smoking habits.

Materials And Methods: Patients with histologically malignant urologic tumors were enrolled in our questionnaire-based study from September 2013 to December 2014 in 2 urology departments.

Background: Acute renal colic (ARC) is an emergency that can mostly be treated conservatively, but can be life threatening in combination with urinary tract infection (UTI). Assessment for infection includes white blood cell (WBC) count and C-reactive protein (CRP), but these parameters are often unspecifically elevated and might lead to antibiotic over-therapy. In times of increasing antibiotic resistance, however, unnecessary antibiotic therapy should be avoided.

Unlabelled: Background/Aims/Objectives: To evaluate the influence of body mass index (BMI) on complications and oncological outcomes in patients undergoing radical cystectomy (RC).

Methods: Clinical and histopathological parameters of patients have been prospectively collected within the "PROspective MulticEnTer RadIcal Cystectomy Series 2011". BMI was categorized as normal weight (<25 kg/m2), overweight (≥25-29.

Purpose: A single-center study was conducted to investigate the impact of sarcopenia as a predictor for 90-day mortality (90 dM) and complications within 90 days after radical cystectomy for bladder cancer.

Methods: In total, 327 patients with preoperative available digital computed tomography (CT) scans of the abdomen and pelvis were identified. The lumbar skeletal muscle index was measured using preoperative abdominal CT to assess sarcopenia.

Purpose: Smoking represents a primary risk factor for the development of urothelial carcinoma (UC) and a relevant factor impacting UC-specific prognosis. Data on the accordant knowledge of UC-patients in this regard and the significance of physicians in the education of UC-patients is limited.

Materials And Methods: Eighty-eight UC-patients were enrolled in a 23-items-survey-study aimed to analyse patient knowledge and awareness of their tumor disease with smoking along with physician smoking cessation counselling.

Background: A multicentre study was conducted to investigate the impact of sarcopenia as an independent predictor of oncological outcome after radical cystectomy for bladder cancer.

Methods: In total, 500 patients with available digital computed tomography scans of the abdomen obtained within 90 days before surgery were identified. The lumbar skeletal muscle index was measured using pre-operative computed tomography.

Background: To evaluate the impact of salvage therapy (ST) on overall survival (OS) in recurrent primary urethral cancer (PUC).

Patients: A series of 139 patients (96 men, 43 women; median age = 66, interquartile range: 57-77) were diagnosed with PUC at 10 referral centers between 1993 and 2012. The modality of ST of recurrence (salvage surgery vs.

Objectives: To evaluate the effect of peri-operative blood transfusion (PBT) on recurrence-free survival, overall survival, cancer-specific mortality and other-cause mortality in patients undergoing radical cystectomy (RC), using a contemporary European multicentre cohort.

Patients And Methods: The Prospective Multicentre Radical Cystectomy Series (PROMETRICS) includes data on 679 patients who underwent RC at 18 European tertiary care centres in 2011. The association between PBT and oncological survival outcomes was assessed using Kaplan-Meier, Cox regression and competing-risks analyses.

Objectives: To investigate the effect of AB0 and Rhesus factor expression blood group systems on outcomes of upper tract urothelial carcinoma patients treated with radical nephroureterectomy.

Patients And Methods: We analyzed data from 271 patients with upper tract urothelial carcinoma who underwent radical nephroureterectomy at 3 German academic institutions. Cox and logistic regression models assessed the association of AB0 blood group antigen and Rhesus factor expression with tumor biologic features and outcomes, respectively.

Background: The benefit of adjuvant chemotherapy (AC) for muscle-invasive urothelial carcinoma of the bladder (UCB) after radical cystectomy (RC) is controversial.

Objective: To assess the effectiveness of AC after RC for muscle-invasive UCB in contemporary European routine practice.

Design, Setting, And Participants: By using a prospectively collected European multicenter database, we compared survival outcomes between patients who received AC versus observation after RC for locally advanced (pT3/T4) and/or pelvic lymph node-positive (pN+) muscle-invasive UCB in 2011.

At the present time, there is no evidence available as to the knowledge of general surgeons regarding multi-resistant pathogens (MRP) and the rational use of antibiotic medication (antibiotic stewardship/ABS) compared with physicians from other disciplines. As part of the MR2 survey (Multiinstitutional Reconnaissance of practice with MultiResistant bacteria - a survey focussing on German hospitals), a questionnaire comprising 4 + 35 items was distributed to urologists, internists, gynaecologists and general surgeons in 18 hospitals. Multivariate regression models were applied to assess the impact of each discipline affiliation on predefined endpoints.
