3.0-T multiparametric magnetic resonance imaging modifies the template of endoscopic, conventional radical prostatectomy in all cancer risk categories.

INTRODUCTION: We aimed to evaluate the diagnostic performance of 3.0-T multiparametric magnetic resonance imaging (mpMRI) in preoperative staging of prostate cancer (PCa) and its influence on the extent of resection during endoscopic radical prostatectomy (ERP) among cancer risk groups. MATERIAL AND METHODS: The data of 154 patients with PCa in whom mpMRI was performed prior to ERP between 2011 and 2015 were included. The initial decision whether to perform neurovascular bundle (NVB) sparing surgery was based on EAU guidelines. mpMRI images were reevaluated prior to prostatectomy to modify the surgical template. Imaging was compared with pathological reports to investigate the diagnostic performance of mpMRI. RESULTS: The surgical template was modified in 69 (44.8%) patients after reevaluation of mpMRI. More preserving NVB sparing was attempted in 17 (11.0%) men, in whom NVB would have been resected if mpMRI had not been available. More aggressive NVB resection was performed in 52 (33.8%) men, in whom innervation would have been spared if basing solely based on guidelines. Among all PCa risk groups mpMRI had an impact on the surgical template with more aggressive surgery in 63.0% and 33.3% of men in the low- and intermediate-risk group, respectively, and more preserving in 21.4% of the high-risk patients. The change in extent of resection was not correlated with a higher risk of positive surgical margins (p = 0.196). CONCLUSIONS: Preoperative mpMRI exerts a significant impact on decision making concerning the extent of resection during ERP irrespective of the PCa risk group.

Extent of lymphadenectomy in patients with bladder cancer undergoing radical cystectomy - a multi-institutional analysis.

Lymph node dissection (LND) performed at radical cystectomy (RC) has therapeutic and staging significance. However, the extent of LND remains controversial. The aim of this study was to analyze surgical patterns and results of LND in a contemporary series of patients with bladder cancer. This is a retrospective analysis of 113 consecutive patients subjected to RC in seven urological centres in the year 2013. The mean age of the cohort was 66.6 years. There were 49 cases of organ confined and 64 cases of locally advanced disease. Study endpoints were: status and extent of LND, number of LNs removed, and number of positive LNs. LND was performed in 102 patients (90.3%). Detailed data on the anatomical extent of LND was available in 82 patients (80.4%). Limited (lLND) and extended LND (eLND) was performed in 68.3% (n = 56) and 31.7% (n = 26) of patients, respectively. Obturator fossa LNs were removed in 84.1%, external iliac in 72.0%, internal iliac in 40.2%, common iliac in 31.7%, and presacral in 15.9% of cases. The median number of LNs removed in the whole study cohort, in patients who underwent lLND, and eLND, was 8.5, 5, and 16.5, respectively. In 28 patients (27.5%), LN metastases were diagnosed, including 6 cases (12.5%) in the organ-confined cohort and 22 cases (34.4%) in the locally advanced disease cohort. LND is an integral part of radical cystectomy in patients with bladder cancer. However, in the majority of patients, the extent of the procedure was suboptimal, potentially negatively affecting the survival and adequacy of pathological staging.

Contralateral adrenal metastasis from renal cell carcinoma with tumor thrombus in the adrenal vein: a case report.

A 64-year-old woman presented with contralateral right adrenal metastasis with adrenal vein thrombus, which was diagnosed many years after left nephrectomy with adrenalectomy due to renal cell cancer. The patient underwent right adrenalectomy with adrenal vein tumor thrombectomy for treatment. The pathologic examination confirmed metastatic clear cell carcinoma. The remote but existing risk of developing contralateral adrenal metastasis (CAM) after primary radical nephrectomy supports the idea of sparing the adrenal gland in suitable patients who undergo radical nephrectomy. Contralateral adrenal metastasis from RCC is a rare finding with the potential benefit of cure after resection. Care must be taken in preoperative diagnostics, as this metastasis is capable of causing inferior vena cava tumor thrombus via the suprarenal venous route. According to our knowledge, our case is the second similar entity described in literature so far.

Infected urachal cyst in a young adult.

The urachus is the remnant of the cloaca, which in adults attaches the bladder dome to the umbilicus. After birth it obliterates and presents as the midline umbilical ligament. Patent urachal anomalies are usually detected in childhood. In adults they occur very rarely and the presentation and diagnosis may be occasionally challenging. We present and discuss the case of an infected urachal cyst found in a 30-year-old adult.

Interobserver variability of Clavien-Dindo scoring in urology.

OBJECTIVES: To assess the interobserver variability of Clavien-Dindo scoring in urology. METHODS: A thematic survey was carried out simultaneously in nine Polish urological centers among 171 responders - 81 urologists and 90 urologists-in-training, made up of 16 women and 155 men. After Clavien-Dindo classification was presented, respondents were asked to grade nine typical urological complications according to Clavien-Dindo classification. Interobserver agreement, reproducibility of answers, as well as the influencing factors were analyzed. Questions in the survey related to complications of variable severity after basic urological operations, including four open, one laparoscopic and four endourological. RESULTS: Agreement on the grade of complication was moderate (κ = 0.45) and it was noticed in 69% of respondents (range 38-87%). No effect of surgical approach (classic vs endoscopic, 70% vs 67%, P = 0.64), or physician professional experience (resident vs urologist, 71% vs 66%, P = 0.77) was observed. The most significant discrepancies were found in cases of local complications after transurethral surgery (accordance in 39%) and laparoscopic radical prostatectomy (accordance in 55%), and in cases of severe general complications after Bricker operation (accordance in 58%). CONCLUSIONS: The variability of Clavien-Dindo classification scoring among urologists is significant. Thus, the Clavien-Dindo classification might require detailing before its eventual implementation in urology, together with appropriate training of specialists. However, despite some disadvantages, the simplicity, reproducibility and logical scheme of the Clavien-Dindo classification make it a promising tool for quality assessment in different fields of urology.

Clinical value of extended pelvic lymph node dissection in patients subjected to radical prostatectomy.

INTRODUCTION: Extended pelvic lymph node dissection (ePLND) is advised to complement radical prostatectomy (RP) in intermediate and high risk prostate cancer patients. AIM: To assess the risk of nodal involvement in patients subjected to laparoscopic radical prostatectomy and to characterize the group of patients with lymph node (LN) metastases. MATERIAL AND METHODS: Data of patients subjected to laparoscopic radical prostatectomy with ePLND between February 2011 and June 2013 were analyzed. The LN that were removed included presacral nodes, common, external and internal iliac nodes and obturator ones. RESULTS: Mean number of removed LNs was 19. Metastases within LN were found in 13 (16.6%) patients. In comparison to those without LN involvement, patients who were found to have LN metastases had a greater number of positive biopsy cores (3.7 vs. 5.3, p < 0.01), maximum percentage of cancer in biopsy core (47.0 vs. 67.6, p < 0.01), greater biopsy and specimen Gleason scores (7.0 vs. 7.7 and 7.0 vs. 7.8) and more frequently advanced clinical and pathological stage. The most frequent landing sites of prostate cancer were obturator and presacral nodes (100% and 38%). Eleven patients (85%) among those with positive LN had locally advanced disease. CONCLUSIONS: The risk of LN metastases in intermediate and high risk prostate cancer patients is significant. Therefore, if radical prostatectomy is chosen, ePLND should be performed. The majority of patients with involvement of pelvic LN have locally advanced disease which would refer them to adjuvant radiation if managed without nodal dissection.

[Analysis of the clinical course of disease and subsequent dialysis therapy in a group of patients with rheumatoid arthritis and end-stage renal disease]. / Analiza klinicznego przebiegu choroby oraz leczenia nerko- zastepczego grupy chorych na reumatoidalne zapalenie stawów.

The chronic nephropathy is often present in pts with rheumatoid arthritis (RA). In the study the authors retrospectively analyzed the clinical course of the disease and outcomes of subsequent dialysotherapy in a group of pts with RA and end-stage renal disease ESRD. During last 5 years ESRD connected with RA was found in 10 (8 F, 2 M) pts out of 325 chronically dialyzed pts (peritoneal dialysis and hemodialysis) representing 3,1% of pts. The mean age at the initiation of dialysotherapy in these pts was 62,8 +/- 10,2 (range 46-76) years. Mean time from the diagnosis of RA to the start of dialysotherapy was 18,8 +/- 11,6 (range 5-40) years. Earlier the patients were treated with many disease modifying antirheumatic drugs (DMARDS) also with glucocorticosteroids and many nonsteroidal anti-inflammatory drugs. It means that they had rather aggressive type of RA. Amyloidosis was histological confirmed in 6 pts (4 F, 2 M). Peritoneal dialysis (PD) was the first choice therapy in 8 pts (2 on APD, 6 on CAPD). The main complication was increased incidence of peritonitis. 3 pts died on PD after 5, 9, 24 months (respectively) of CAPD treatment. 3 pts were transferred to HD after 5, 15, 18 (respectively) months of CAPD because of recurrent peritonitis. 2 pts up to date continue PD (one 12 months, the second 46 months on CAPD). In 5 pts who needed hemodialysis treatment there have been very serious problems with permanent vascular access formation. All used permanent indwelling catheters (Permcath). We concluded that: occurrence of ESRD in pts with RA was connected with aggressive type of disease. Pts with RA represent a dialysis group that is particularly prone to complications of PD (enteric peritonitis) and HD (vascular access problems). It seems to be connected with secondary vasculitis often found in pts with aggressive type of RA.
