Age above 70 years and Charlson Comorbidity Index higher than 3 are associated with reduced survival probabilities after radical cystectomy for bladder cancer. Data from a contemporary series of 334 consecutive patients.

Objective: To assess the joint effect of age and comorbidities on clinical outcomes of radical cystectomy (RC).Methods: 334 consecutive patients undergoing open RC for bladder cancer (BC) during the years 2005-2015 were analyzed. Pre-, peri- and post-operative parameters, including age at RC (ARC) and Charlson Comorbidity Index (CCI), were evaluated. Overall and cancer-specific survivals (OS, CSS) were assessed by univariate and multivariate modelling. Furthermore, a three-knot restricted cubic spline (RCS) was fitted to survival data to detect dependency between death-rate ratio (HR) and ARC. Results: Median follow-up time was 3.8 years (IQR = 1.3-7.5) while median OS was 5.9 years (95%CL = 3.8-9.1). Globally, 180 patients died in our cohort (53.8%), 112 of which (62.2%) from BC and 68 patients (37.8%) for unrelated causes. After adjusting for preoperative, pathological and perioperative parameters, patients with CCI > 3 showed significantly higher death rates (HR = 1.61; p = 0.022). The highest death rate was recorded in ARC = 71-76 years (HR = 2.25; p = 0.034). After fitting an RCS to both OS and CSS rates, two overlapping nonlinear trends, with common highest risk values included in ARC = 70-75 years, were observed. Conclusions: Age over 70 years and CCI > 3 were significant factors limiting the survival of RC and should both be considered when comparing current RC outcomes

Selective synthesis of methyl dithienyl-glycolates

An efficient selective synthesis of methyl dithienyl-glycolates has been developed. The interest of this two steps protocol resides in the possibility of synthesized either methyl 2,2-dithienyl glycolate \u2013 the target intermediate for the preparation of anticholinergic agents \u2013 or its regio-isomer methyl 2,3-dithienyl glycolate \u2013 the most critical precursor of anticholinergic drug impurity

A Giant Paratesticular Liposarcoma: Case Report and Literature Review

Liposarcoma of the spermatic cord (LSC) is a very rare disease. In literature, are reported less than 350 cases. Genitourinary sarcomas account for <5% of all soft-tissue sarcomas and <2% of malignant urologic tumours. An inguinal mass is the clinical presentation, which can mimic a hernia or hydrocele. Since it is such a rare disease, there are insufficient data on chemotherapy and radiotherapy, and in any case, the data come from low-level scientific evidence. Here, we report the case of a patient who came to the observation for a giant inguinal mass, in which a definitive diagnosis was obtained with the histological examination

En Bloc Thulium Laser Enucleation of the Prostate: A Step-by-Step Guide to Improve Enucleation Time and Efficiency for Endoscopic Enucleation of Prostatic Adenoma

OBJECTIVE: To present a reproducible step-by-step approach to en bloc thulium laser enucleation of the prostate (ThuLEP) for benign prostatic hyperplasia surgical treatment. Laser adenoma enucleation is nowadays a recognized surgical treatment for benign prostatic enlargement. Some variants to the classical 3-lobes laser technique have been proposed, in order to overcome the main concerns regarding the original procedure.1-4 After a vast experience with the 3-lobes ThuLEP, we developed our own en bloc enucleation technique. METHODS: The capsular plane is identified only once, at the level of the prostatic apex, at 5 o'clock; this plane is followed ascending towards the bladder neck, separating the left lobe from the prostatic capsule from 5 to 11 o'clock. The right and median lobes are then enucleated following the same plane clockwise and the 2 planes are joined anteriorly at 11 o'clock. Finally, enucleation is completed by incising the remaining mucosal flap from 10 to 2 o'clock. We have already proved the clear advantages provided by this technique compared to the "3-lobes" enucleation.5 RESULTS: Our single-center experience with this technique includes 140 procedures performed up to June 2018. Mean prostatic adenoma volume was 66.7 mL (range 20-220 \ub1 32.85 standard deviation [SD]). Mean total surgical time was 60.93 minutes (25-133 \ub1 23.6 SD); mean enucleation time was 18.3 minutes (8.2-36.53 \ub1 5.62 SD), mean enucleation time normalized per adenoma gram was 0.32 min/g (0.12-0.8 \ub1 0.15 SD) and mean energy needed for the enucleation normalized per adenoma gram was 1852.13 J/g (689-6129 \ub1 862.4 SD). Only 1 case of reintervention for clot evacuation (Clavien grade IIIb) was necessary. CONCLUSION: En bloc ThuLEP provides an anatomical approach for endoscopic enucleation of prostatic adenoma. We believe that this sequence optimizes efficiency and efficacy in a reproducible way

Magnetic resonance spectroscopy in Parkinson's disease and parkinsonian syndromes

This paper looks at the use of magnetic resonance spectroscopy (MRS) for diagnostic and research purposes in Parkinson’s disease and parkinsonian syndromes. The review considers both proton MRS (1H MRS) and phosphorus MRS (31 P MRS) studies. MRS is useful for diagnostic purposes, helping to differentiate Parkinson’s disease from other parkinsonian syndromes. Even more usefully, MRS can be used for non invasive in vivo human researc

The Tomato Model

OBJECTIVES Percutaneous renal access (PCA) is one of the most difficult intervention in endourology. Handson training is a useful tool for a good understanding of the puncturing technique, reducing the learning curve, and lowering risks of complications during first procedures. The ideal surgical simulator should efficiently improve trainees' skills, be easily accessible, low-cost, and realistic. We aim to present novel fluoroscopy-guided PCA simulator named TOMATO model.MATERIALS AND METHODS The model can be easily built in few minutes using low-cost items: yoga mat, cotton wool, forceps, needle-driver, scalpel, 0 silk suture, chiba needle, small pebble (1 cm ca) and a few kidney-shaped tomatoes. The yoga mat is fold in half, sutured with silk, placed on the operating table, and thanks to the friction created between the mat and sheet underneath there is no need for other fixating methods. Once placed inside the yoga mat, the tomato is held still in the position by the cotton wool, which is placed around the vegetable. The tomato imitates the real renal structure. Therefore is ideal for this use, and there is no need for liquid-contrast enhancement. The goal is achieved when the operator manages to move the pebble with chiba needle during pulsed fluoroscopy. The model was tested 3 times by 3 endourologists and by 10 residents in training with no experience as first operators. A 7-items questionnaire (1-10 rating scale) was administered to the participants in order to evaluate the utility of the model. Trainees' kidney access time (KAT) and radiation time (RT) were assessed at the first use and after 1 hour of training (circa 15 attempts to reach the target per resident).RESULTS The model allowed residents' significant reduction of the KAT and RT. KAT passed from 114 (144.25-89) to 72.5 (97.25-49.5) seconds (P = .04) while RAT passed from 82 (89.75-56) to 51.5 (60.25-35.75) seconds (P < .001). The residents particularly appreciated the high-fidelity reproduction of the anatomy that the model offers, and its' usefulness for learning the puncturing technique, giving it 8.5 and 10 points, while the same items were rated 7.7, and 9.3 by the experts, respectively. Trainees felt that their skills could be improved by using this model. The main issue was finding the materials mimicking the real-life tissues and their different characteristics.CONCLUSIONS TOMATO model might be a helpful and creative way to start learning the steps of kidney puncturing using low-cost materials and we believe its' strength is being easily reproducible in all urology units.
