Ultrasonographic findings in dual kidney transplantation.

INTRODUCTION: Organ shortage has led to using grafts from expanded criteria donors (ECD). Double kidney transplantation is an accepted strategy to increase the donor pool, using organs from an ECD which are not acceptable for single kidney transplantation (SKT). Aim of this retrospective study was to analyse the role of colour Doppler ultrasound (CDUS) in the diagnosis of major surgical complications in DKT, performed with unilateral or bilateral placement. MATERIALS AND METHODS: From 2000 to 2011 we performed 54 DKT. Unilateral placement of both kidneys was done in 26 patients and bilateral DKT in 28, through two separate Gibson incisions (18) or one midline incision (10). Each patient underwent at least 3 CDUS before hospital discharge. The main surgical complications, discovered initially thanks to ultrasound (US), were hydronephrosis from ureteral obstruction, lymphocele and deep venous thrombosis (DVT). RESULTS: Mean follow-up was 42.7 months. Good postoperative renalfunction was demonstrated in 25 patients (46.3%), while delayed graft function occurred in 29 (53.7%). US showed ureteral obstruction requiring surgery in 5 unilateral DKT while no patient subjected to bilateral DKT developed severe hydronephrosis. Lymphoocele, surgically drained, was demonstrated in 6 bilateral DKT with a midline incision, 2 bilateral DKT with two separate incisions and 3 unilateral DKT. CDUS also enabled diagnosis of 2 cases of DVT in ipsilateral DKTs. CONCLUSIONS: CDUS provides useful information in patients with DKT, allowing the detection of clinically unsuspected unilateral diseases. US study of our patients demonstrated that unilateral DKTs are more susceptible to the development of DVT and ureteral stricture, while the incidence of voluminous lymphocele is more frequent in bilateral DKT through a single midline incision. In this scenario, all patients undergoing DKT should be carefully monitored by US after surgery.

Follow-up of elderly patients with urogenital cancers: Evaluation of geriatric care needs and related actions.

OBJECTIVES: To investigate a comprehensive geriatric assessment (CGA) with subsequent investigation of healthcare patterns in older patients with urological cancers undergoing initial surgery or radiotherapy, to verify the usefulness of the incorporation of geriatric principles in future care plans. MATERIAL AND METHODS: This is a prospective cohort study. From November 2011 to March 2015, CGA was offered to all patients aged 70+ years treated with radiotherapy or surgery at seven tertiary centers. Patients were classified as fit, vulnerable, or frail according to Balducci's definition. CGA and follow-up data were collected by two trained evaluators at 6 and 12months. The information collected was not available to the caring physicians during follow-up. RESULTS: CGA was performed in 453 patients with prostate cancer (295), bladder cancer (126), or kidney cancer (32). 40% of patients with prostate cancer were fit, 47% vulnerable, and 13% frail. The corresponding values for renal cancer were 25%, 40%, and 34%, and for bladder cancer, 21%, 42%, and 37%. During follow-up, 60% of patients with cardiac diseases, 42% of those with diabetes/other metabolic disorders, 35% of those with hypertension, and 35% of those with respiratory diseases were followed by a specialist (for these severe/extremely severe comorbidities). Of 16 patients with ADL impairment and 63 with IADL impairment, only 4 (25%) and 6 (10%), respectively, were referred to a rehabilitation service. Only one case was referred to a geriatrician. CONCLUSIONS: Appropriate clinical care patterns are advisable to improve quality of survivorship in older patients with urological cancers.

[Positive surgical margin status after minimally invasive radical prostatectomy: a multicenter study]. / Margini chirurgici positivi dopo prostatectomia radicale mini-invasiva: studio multicentrico.

UNLABELLED: UNLABELLED: The aim of our study is to evaluate the status of positive margins (PSMs) comparing their incidence between aparoscopic radical prostatectomy (LRP) and robot assisted radical prostatectomy (RARP) in centers with medium case-load (50-150 cases/year). We also analyzed the correlations between surgical technique, nerve-sparing approach (NS), and incidence of PSMs, stratifying our results by pathological stage. MATERIALS AND METHODS: We analyzed 1992 patients who underwent RP in various urologic centers. We evaluated the incidence of PSMs, and then we compared the stage-related incidence of PSMs, for both the techniques. RESULTS: We did not find a statistically significant difference between the two surgical modalities in the study regarding the overall incidence of PSMs. CONCLUSIONS: In our retrospective study, we did not find any difference in terms of PSMs in RARP versus LRP. Our PSMs were not negligible, particularly in pT3 stages, compared with high-volume centers; surgical experience and patients' selection can be a possible explanation.

Perineural invasion as a predictor of extraprostatic extension of prostate cancer: a systematic review and meta-analysis.

A systematic review of the literature was performed to assess the relationship between the presence of perineural invasion (PNI) at prostate biopsy and extraprostatic extension (EPE) of prostate cancer. In August 2012, Medline, Embase, Scopus and Web of Science databases were searched. A "free-text" protocol using the terms "perineural invasion prostate cancer" was applied. Studies published only as abstracts and reports from meetings were not included in this review. In total, 341 records were retrieved from Medline, 507 from Embase, 374 from Scopus and 65 from the Web of Science database. The records were reviewed to identify studies correlating the presence of PNI with that of EPE. A cumulative analysis was conducted using Review Manager software v. 5.1 (Cochrane Collaboration, Oxford, UK). In univariate analysis, PNI showed a statistically significant association with pT3 tumours (p < 0.00001), which could be observed for both pT3a (p < 0.0001) and pT3b (p < 0.0001). In conclusion, the cumulative analysis shows a statistically significant higher incidence of EPE in patients who had PNI at needle biopsy. The main limitation of the analysis was that it was not possible to perform a multivariate analysis. Further attempts to build a nomogram for the prediction of EPE could include the presence of PNI at needle biopsy.
