Non-muscle invasive bladder cancer: Are epicrises the ‘Bermuda Triangle’ of information transfer?
2017
Introduction The aim of the study was to collect information regarding the quality of communication of risk-determining factors or risk profile, and the guideline conformity of recommendations for adjuvant treatment in patients with non-muscle invasive bladder cancer (NMIBC) between clinical and ambulatory urologists. Material and methods At three German urological clinics during the period between 2012-2014, epicrises of 1,033 NMIBC-patients were retrospectively summarised to 505 tumour episodes (tumour resection including any re-resections) and analysed regarding the endpoints 1) risk profile is explicitly named or recorded risk factors are sufficient for the determination of risk profile…
The “bouquet of flowers” appearance in medullary sponge kidney
2018
The “bouquet of flowers” appearance is a radiological finding described for the intravenous pyelography (IVP) diagnosis of medullary sponge kidney (MSK). It refers to contrast pooling in dilated tubular structures in renal papillae, giving a striated pattern to the renal medulla, which resembles a “bouquet of flowers”
Percutaneous Stone Manipulation
1981
Percutaneous stone manipulation by direct ultrasound disintegration, extraction or chemolysis was done on 34 patients. A total of 15 patients presented with an operatively established nephrostomy, while percutaneous nephrostomy and subsequent dilation of the nephrostomy channel were done in 19. The rate of complete stone clearance was 19 of 20 stones after percutaneous nephrostomy and 8 of 16 stones in the group with an operatively established nephrostomy. The primary goal, to remove obstructing pelvic stones, was achieved in all cases. There were no untoward side effects, such as back pressure damage owing to flushing of the collecting system during ultrasound disintegration, or persistent…
Incidence, Risk Factors and Management of Symptomatic Lymphoceles after Radical Retropubic Prostatectomy
2017
Abstract Introduction We investigated the incidence, clinical course and risk factors for symptomatic lymphoceles after radical retropubic prostatectomy with pelvic lymph node dissection. Moreover, we explored parameters for the failure of percutaneous lymphocele drainage. Methods The incidence of symptomatic lymphoceles in patients with prostate cancer who underwent radical retropubic prostatectomy with pelvic lymph node dissection in our department between 2008 and 2013 was investigated retrospectively. The occurrence of lymphoceles was correlated with several clinical and histopathological parameters. In addition, logistic regression analysis was performed to assess the value of independ…
Autonomic nervous control of the urinary bladder
2013
The autonomic nervous system plays an important role in the regulation of the urinary bladder function. Under physiological circumstances, noradrenaline, acting mainly on β(3) -adrenoceptors in the detrusor and on α(1) (A) -adrenoceptors in the bladder outflow tract, promotes urine storage, whereas neuronally released acetylcholine acting mainly on M(3) receptors promotes bladder emptying. Under pathophysiological conditions, however, this system may change in several ways. Firstly, there may be plasticity at the levels of innervation and receptor expression and function. Secondly, non-neuronal acetylcholine synthesis and release from the urothelium may occur during the storage phase, leadi…
Coronavirus disease 2019 in chronic kidney disease
2020
Abstract The clinical spectrum of coronavirus disease 2019 (COVID-19) infection ranges from asymptomatic infection to severe pneumonia with respiratory failure and even death. More severe cases with higher mortality have been reported in older patients and in those with chronic illness such as hypertension, diabetes or cardiovascular diseases. In this regard, patients with chronic kidney disease (CKD) have a higher rate of all-type infections and cardiovascular disease than the general population. A markedly altered immune system and immunosuppressed state may predispose CKD patients to infectious complications. Likewise, they have a state of chronic systemic inflammation that may increase …
Urology practice during COVID-19 pandemic
2020
The severe acute respiratory syndrome coronavirus 2 and the disease it causes, coronavirus disease 2019 (COVID-19) is generating a rapid and tragic health emergency in Italy due to the need to provide assistance to an overwhelming number of infected patients and, at the same time, treat all the non-deferrable oncological and benign conditions. A panel of Italian urologists has agreed on possible strategies for the reorganization of urological routine practice and on a set of recommendations that should facilitate the process of rescheduling both surgical and outpatient activities during the COVID-19 pandemic and in the subsequent phases. This document could be a valid tool to be used in rou…
Renal cell carcinoma with inferior vena cava involvement: Prognostic effect of tumor thrombus consistency on cancer specific survival
2016
Background Renal cell carcinoma forming a venous tumor thrombus (VTT) in the inferior vena cava (IVC) has a poor prognosis. Recent investigations have been focused on prognostic markers of survival. Thrombus consistency (TC) has been proposed to be of significant value but yet there are conflicting data. The aim of this study is to test the effect of IVC VTT consistency on cancer specific survival (CSS) in a multi-institutional cohort. Methods The records of 413 patients collected by the International Renal Cell Carcinoma–Venous Thrombus Consortium were retrospectively analyzed. All patients underwent radical nephrectomy and tumor thrombectomy. Kaplan–Meier estimate and Cox regression analy…
Molecular genetics of Staphylococcus epidermidis biofilms on indwelling medical devices.
2005
Staphylococcus epidermidis is an opportunistic pathogen associated with foreign body infections and nosocomial sepsis. The pathogenicity of S. epidermidis is mostly due to its ability to colonize indwelling polymeric devices and form a thick, multilayered biofilm. Biofilm formation is a major problem in treating S. epidermidis infection as biofilms provide significant resistance to antibiotics and to components of the innate host defenses. Various cell surface associated bacterial factors play a role in adherence and accumulation of the biofilm such as the polysaccharide intercellular adhesin and the autolysin AtlE. Furthermore, recent studies have shown that global regulators such as the …
Stauffer’s Syndrome in Patient with Metastatic Prostate Cancer
2019
Cholestasis is a symptom that can be present in many conditions, such as bile duct obstruction by malignant mases, obstruction by gallstone, acute and chronic viral hepatitis, and autoimmune disorders, such as primary biliary and sclerosing cholangitis. Stauffer syndrome is a rare type of paraneoplastic syndrome that presents as cholestasis with absence of underlying disease. Classically Stauffer syndrome has been described in renal cell cancer patients. In literature cholestasis as manifestation of paraneoplastic syndrome has also been described in patients with prostate adenocarcinoma and pancreatic and bronchogenic carcinoma. Conclusions. Stauffer syndrome should be kept in mind in patie…
