To evaluate the oncological results, associated complications, and postoperative health-related quality of life (HR-QoL) in patients treated with partial cystectomy (PC) for muscle-invasive bladder cancer (MIBC). 27 patients who underwent open PC for cT2 MIBC were included. A simple Cox’s proportional hazards regression model was used to assess the association of several potential prognostic factors with survival. Postoperative HR-QoL was assessed with the EORTC (European Organisation for the Research and Treatment of Cancer) QLQ-C30 questionnaire version 3.0. Final pathological tumour stages in PC specimen were: pT0: 18.5%, non-MIBC: 3.7%, MIBC: 74.1%, pCIS: 14.8%. Estimated 5-year overall- and progression-free survival rates were 53.7% and 62.1%. Five (18.5%) patients experienced local recurrence with MIBC. Overall, the salvage cystectomy rate was 18.5%. The 90-day mortality rate was 0%. Significant risk factors for progression-free survival were vascular invasion (HR 5.33) and tumour multilocularity (HR 4.5) in the PC specimen, and a ureteric reimplantation during PC (HR 4.53). The rates of intraoperative complications, 30- and 90-day major complications were 7.4%, respectively and 14.8% for overall long-term complications. Postoperatively, median (IQR) global health status and QoL in our PC cohort was 79.2 (52.1–97.9). Open PC can provide adequate cancer control of MIBC with good HR-QoL in highly selected cases. Open PC can lead to long-term bladder preservation and shows an acceptable rate of severe perioperative complications, even in highly comorbid patients.

Fournier’s gangrene (FG) is a life-threatening infection of the genital, perineal, and perianal regions with a morbidity range between 3 and 67%. Our aim is to report our experience in treatment of FG and to assess whether three different scoring systems can accurately predict mortality and morbidity in FG patients. All patients that were treated for FG at the Department of Urology of the University Hospital Basel between June 2012 and March 2017 were included and assessed retrospectively by chart review. Furthermore, we calculated Fournier’s Gangrene Severity Index (FGSI), the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC), and the neutrophil–lymphocyte ratio (NLR) in every patient and assessed whether those scores correlate with the patients’ morbidity and mortality. Twenty patients were included, with a median (IQR) age of 66 (46–73) years. Fifteen of twenty (75%) patients required treatment on an intensive care unit, and three died (mortality rate: 15%). The mean FGSI, LRINEC, and NLR scores were 13.0, 9.3, and 45.3 for non-survivors and 7.7, 6.5, and 26 for survivors, respectively. None of the risk scores correlated significantly with mortality; however, all three significantly correlated with infection- and surgically-induced morbidity. In our series, Fournier’s gangrene was associated with a mortality rate of 15% despite maximum multidisciplinary therapy at a specialized center. All risk scores were able to predict the morbidity of the disease in terms of local extent and the required surgical measures.
To investigate the reliability with which healthcare professionals with different levels of expertise are able to impart the exact location of prostate cancer (PCA) after (A) reading written magnetic resonance imaging (MRI) reports, (B) attending MRI presentations in multidisciplinary team meetings (MDT), and (C) examining 3D printed prostate models, which represents a new technology to describe the location of PCA lesions. We used three different PCA cases to assess the three information tools. Construct validation was performed using two healthcare groups with different levels of expertise: (1) Nine expert urologists in PCA, and (2) nine medical students. After each information tool, the study participants plotted the tumor location in a 2-dimensional prostate diagram. A scoring system was established to evaluate the drawings in terms of accuracy of plotting tumor position. Data are shown as median scores with interquartile range. Within the expert group, no significant difference was seen in the overall scoring results between the information tools (p = 0.34). Medical students performed significantly worse with MDT information (p = 0.03). Experts performed better in all three information tools compared to students, resulting in a significantly 25% higher overall total score (25.0[22.3–26.7] vs. 20.0[15.0–24.0], p<0.001). The difference was largest after MDT information, with experts showing a 49% better scoring (p<0.001), and second largest with the 3D printed models, showing a 17% better scoring of the experts (p = 0.07). No difference was found in the written MRI report scoring results between experts and students. 3D printed models provided better orientation guide to medical students compared to MDT MRI presentations. This indicates that the 3D printed models might be easier to understand than the current gold standard MDT conferences. Therefore, 3D models may play an increasingly important role in providing guidance for orientation for less experienced individuals, such as surgical trainees.
Nephron-sparing surgery (NSS) remains gold standard for the treatment of localised renal cell cancer (RCC), even in case of a normal contralateral kidney. Compared to radical nephrectomy, kidney failure and cardiovascular events are less frequent with NSS. However, the effects of different surgical approaches and of zero ischaemia on the postoperative reduction in renal function remain controversial. We aimed to investigate the relative short- and long-term changes in estimated glomerular filtration rate (eGFR) after ischaemic or zero-ischaemic open (ONSS) and laparoscopic NSS (LNSS) for RCC, and to analyse prognostic factors for postoperative acute kidney injury (AKI) and chronic kidney disease (CKD) stage ≥3. Data of 444 patients (211 LNSS, 233 ONSS), including 57 zero-ischaemic cases, were retrospectively analysed. Multiple regression models were used to predict relative changes in renal function. Natural cubic splines were used to demonstrate the association between ischaemia time (IT) and relative changes in renal function. IT was identified as significant risk factor for short-term relative changes in eGFR (ß = − 0.27) and development of AKI (OR, 1.02), but no effect was found on long-term relative changes in eGFR. Natural cubic splines revealed that IT had a greater effect on patients with baseline eGFR categories ≥G3 concerning short-term decrease in renal function and development of AKI. Unlike LNSS, ONSS was significantly associated with short-term decrease in renal function (ß = − 13.48) and development of AKI (OR, 3.87). Tumour diameter was associated with long-term decrease in renal function (ß = − 1.76), whereas baseline eGFR was a prognostic factor for both short- (ß = − 0.20) and long-term (ß = − 0.29) relative changes in eGFR and the development of CKD stage ≥3 (OR, 0.89). IT is a significant risk factor for AKI. The short-term effect of IT is not always linear, and the impact also depends on baseline eGFR. Unlike LNSS, ONSS is associated with the development of AKI. Our findings are helpful for surgical planning, and suggest either the application of a clampless NSS technique or at least the shortest possible IT to reduce the risk of short-time impairment of the renal function, which might prevent AKI, particularly regarding patients with baseline eGFR category ≥G3.
Background: Urinary calprotectin has been identified as a promising biomarker for acute kidney injury. To date, however, the time-dependent changes of this parameter during acute kidney injury remain elusive. The aim of the present work was to define the time-course of urinary calprotectin secretion after ischaemia/reperfusion-induced kidney injury in comparison to neutrophil gelatinase—associated lipocalin, thereby monitoring the extent of tubular damage in nephron sparing surgery for kidney tumours. Methods: The study population consisted of 42 patients. Thirty-two patients underwent either open or endoscopic nephron sparing surgery for kidney tumours. During the surgery, the renal arterial pedicle was clamped with a median ischaemic time of 13 minutes (interquartile range, 4.5–20.3 minutes) in 26 patients. Ten retro-peritoneoscopic living donor nephrectomy patients and 6 nephron sparing surgery patients in whom the renal artery was not clamped served as controls. Urinary calprotectin and neutrophil gelatinase—associated lipocalin concentrations were repeatedly measured by enzyme-linked immunosorbent assay and assessed according to renal function parameters. Results: Urinary concentrations of calprotectin and neutrophil gelatinase—associated lipocalin increased significantly after ischaemia/reperfusion injury, whereas concentrations remained unchanged after nephron sparing surgery without ischaemia/reperfusion injury and after kidney donation. Calprotectin and neutrophil gelatinase—associated lipocalin levels were significantly increased 2 and 8 hours, respectively, post-ischaemia. Both proteins reached maximal concentrations after 48 hours, followed by a subsequent persistent decrease. Maximal neutrophil gelatinase—associated lipocalin and calprotectin concentrations were 9-fold and 69-fold higher than their respective baseline values. The glomerular filtration rate was only transiently impaired at the first post-operative day after ischaemia/reperfusion injury (p = 0.049). Conclusion: Calprotectin and neutrophil gelatinase—associated lipocalin can be used to monitor clinical and sub-clinical tubular damage after nephron sparing surgery for kidney tumours. Urinary calprotectin concentrations start rising within 2 hours after ischaemia/reperfusion-induced kidney injury.
