Organ harvesting as a mandatory training step of all PGY1 and PGY2 surgical residents

To the Editor, Good surgical training is essential for the formation of excellent surgeons, consequently providing the best possible care for our patients in the future. Considering the increase in surgeon shortage over the last two decades (estimated between 14,300 and 23,400 by the year 2032 only in the US), it is important for filling the national health system's needs as well [...]

Urology apps: overview of current types and use

CITATION:Mantica G, Malinaric R, Dotta F, et al. Urology apps: overview of current types and use. Cent European J Urol. 2020; 73: 369-372.Introduction In recent years numerous applications have been developed with different purposes, aimed both at simplifying the lives of doctors and patients also within the urological field. Material and methods In January 2020 we conducted a search in the Apple App Store and Google Play Store. Results A total of 521 apps were reviewed, an increase of 8 times as compared to the last complete available review of eight years ago. Most of the urological apps are geared towards the patient and provide information and services to improve the understanding and treatment of different diseases. Some of these apps also get the patient directly in touch with healthcare staff allowing for an improvement in doctor-patient communication. Conclusions Although the usefulness of many of these tools is undoubted, the problem of scientific validation, content control and privacy are not yet solved

Extraperitoneal cystectomy with ureterocutaneostomy derivation in fragile patients - should it be performed more often?

Introduction and objectives: Radical cystectomy (RC) continues to be standard of care for muscle-invasive bladder cancer and recurrent or refractory nonmuscle invasive bladder cancer. Unfortunately, it has high rates of perioperative morbidity and mortality. One of the most important predictors of postoperative outcomes is frailty, while the majority of complications are diversion related. The aim of our study was to evaluate safety of extraperitoneal cystectomy with ureterocutaneostomy in patients considered as frail. Materials and methods: We retrospectively collected data of frail patients who underwent extraperitoneal cystectomy with ureterocutaneostomy from October 2018 to August 2020 in a single center. We evaluated frailty by assessing patients' age, body mass index (BMI), nutritional status by Malnutrition Universal Screening Tool, overall health by RAI (Risk Analysis Index) and ASA (American Society of Anaesthesiologists) score, and laboratory analyses. We observed intraoperative outcomes and rates of perioperative (within 30 days) and early postoperative (within 90 days) complications (Clavien-Dindo classification). We defined extraperitoneal cystectomy with ureterocutaneostomy as safe if patients did not develop Clavien Dindo IIIb, or worse, complication. Results: A total of 34 patients, 3 female and 31 male, were analyzed. The median age was 77, BMI 26, RAI 28, ASA 3 and the majority had preexisting renal insufficiency. Blood analyses revealed presence of severe preoperative hypoalbuminemia and anemia in half of our cohort. Intraoperative median blood loss was 250 cc, whilst operative time 245 min. During perioperative period 60% of our cohort developed Clavien Dindo II complication and during early postoperative period 32% of patients required readmission. One death occurred during early postoperative period (2.9%). After 12 months of follow-up, we observed stability of the renal function for most patients. Conclusions: We believe that extraperitoneal cystectomy with ureterocutaneostomy could be considered as a treatment option for elderly and/or frail patients

How long should we follow patients managed for muscle-invasive bladder cancer? Lesson learned from a recent clinical practice

To the Editor, The exact time to stop bladder cancer patient's follow-up is not well known and there is not a clear recommendation on if and when stop to follow a patient managed for muscle invasive bladder cancer (MIBC). Major urological guidelines do not provide a precise indication on the timing of follow-up, and there is currently no real consensus on optimal time schedule [...]

Transurethral endoscopic approach for large bladder diverticula: Evaluation of a large series

Objective: To present the results of the largest series of patients with bladder diverticula > 4 cm managed with an endoscopic approach and give tips about the execution of the procedure. Materials and methods: Data of male patients undergone the endoscopic approach for an acquired bladder diverticula > 4 cm from December 2004 to August 2018 were prospectively collected and retrospectively analyzed. The description of the monopolar and bipolar techniques are provided. The success of the procedure was defined as the reduction of the diverticula for more of the 80% of its initial diameter documented at the 3-months follow-up imaging. Continuous variables with nonparametric distribution were compared using the Mann-Whitney test, while frequencies of categorical variables were compared between groups by Fisher\u2019s exact test with significance level set at 0.05. Results: Thirty-nine patients with a mean (+/- SD) age at surgery of 69.4 \ub1 8.8 years were enrolled, for an equal number of diverticula managed. The mean diverticular size was 75.1 \ub1 24.5 millimeters. The mean operative time was 65 \ub1 21.9 minutes including the prostate surgery. Twelve patients (30.8%) were managed with bipolar energy, the others with monopolar. The success of the procedure was achieved in 30 patients (76.9% - 7 bipolar and 23 monopolar - p = 0.66). Conclusions: The endoscopic approach might be considered as a useful option for patients with a large bladder diverticulum who are at risk for major or laparoscopic procedures

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.

Bladder cancer histological variants: which parameters could predict the concordance between transurethral resection of bladder tumor and radical cystectomy specimens?

Introduction The concordance rate of bladder cancer (BCa) histological variants (HV) between transurethral resection of bladder tumor (TURBT) and radical cystectomy (RC) is sub-optimal and is unclear which factors may influence it. The aim of this study was to identify factors that may be correlated to a higher TURBT-RC concordance rate.Material and methods Consecutive patients who had undergone RC between 2000 and 2019 at a single Institution with pathological evidence of HV were included. Patients with diagnosis of HV both at RC and at the previous TURBT were enlisted in the TURBT-RC Concordance Group (CG), whereas patients with only evidence of HV at RC in the TURBT-RC Non-Concordance Group (NCG). Surgical factors evaluated were the source of energy (mono-vs bipolar), surgeon's experience (= 100), execution of re-TURBT, number and size of specimens at TURBT.Results A total of 81 patients were included, 49 (60.5%) in the CG and 32 (39.5%) in the NCG. Among the surgical factors, maximal core length (MCL) was significantly higher in the CG (12.5 vs 10 mm, p = 0.014) (Table 1). At uni-and multivariable analyses, MCL>10 mm represented an independent predictor of concordance [OR 2.95; CI (1.01-8.61); p = 0.048]. Tumor recurrence, focality and dimension, source of energy, surgeon's experience, performance of re-TURBT and total number of specimens at TURBT did not significantly predict the concordance.Conclusions Longer specimens at TURBT yield a higher chance to detect HV before RC. In this light, improving the quality of bladder resection means improving the management of BCa

Efficacy of High-Resolution Preoperative 3D Reconstructions for Lesion Localization in Oncological Colorectal Surgery&mdash;First Pilot Study

When planning an operation, surgeons usually rely on traditional 2D imaging. Moreover, colon neoplastic lesions are not always easy to locate macroscopically, even during surgery. A 3D virtual model may allow surgeons to localize lesions with more precision and to better visualize the anatomy. In this study, we primary analyzed and discussed the clinical impact of using such 3D models in colorectal surgery. This is a monocentric prospective observational pilot study that includes 14 consecutive patients who presented colorectal lesions with indication for surgical therapy. A staging computed tomography (CT)/magnetic resonance imaging (MRI) scan and a colonoscopy were performed on each patient. The information gained from them was provided to obtain a 3D rendering. The 2D images were shown to the surgeon performing the operation, while the 3D reconstructions were shown to a second surgeon. Both of them had to locate the lesion and describe which procedure they would have performed; we then compared their answers with one another and with the intraoperative and histopathological findings. The lesion localizations based on the 3D models were accurate in 100% of cases, in contrast to conventional 2D CT scans, which could not detect the lesion in two patients (in these cases, lesion localization was based on colonoscopy). The 3D model reconstruction allowed an excellent concordance correlation between the estimated and the actual location of the lesion, allowing the surgeon to correctly plan the procedure with excellent results. Larger clinical studies are certainly required

Intravesical Therapy for Non-Muscle-Invasive Bladder Cancer: What Is the Real Impact of Squamous Cell Carcinoma Variant on Oncological Outcomes?

: Background and Objectives: To evaluate the oncological impact of squamous cell carcinoma (SCC) variant in patients submitted to intravesical therapy for non-muscle-invasive bladder cancer (NMIBC). Materials and Methods: Between January 2015 and January 2020, patients with conventional urothelial NMIBC (TCC) or urothelial NMIBC with SCC variant (TCC + SCC) and submitted to adjuvant intravesical therapies were collected. Kaplan-Meier analyses targeted disease recurrence and progression. Uni- and multivariable Cox regression analyses were used to test the role of SCC on disease recurrence and/or progression. Results: A total of 32 patients out of 353 had SCC at diagnosis. Recurrence was observed in 42% of TCC and 44% of TCC + SCC patients (p = 0.88), while progression was observed in 12% of both TCC and TCC + SCC patients (p = 0.78). At multivariable Cox regression analyses, the presence of SCC variant was not associated with higher rates of neither recurrence (p = 0.663) nor progression (p = 0.582). Conclusions: We presented data from the largest series on patients with TCC and concomitant SCC histological variant managed with intravesical therapy (BCG or MMC). No significant differences were found in term of recurrence and progression between TCC and TCC + SCC. Despite the limited sample size, this study paves the way for a possible implementation of the use of intravesical BCG and MMC in NMIBC with histological variants
