Radical prostatectomy (RP) in patients on continuous ambulatory peritoneal dialysis (CAPD) is a challenging procedure. The following key points need to be considered: the peritoneal cavity integrity, adjustment of the trocar positions to the peritoneal dialysis (PD) tube location, and the oncological and functional outcomes. We present a clinical case of a patient on CAPD, incidentally diagnosed with prostate cancer (PCa) during the pre-transplant evaluation.

According to the WHO classification, mesenchymal tumors of the kidney are divided into mesenchymal tumors occurring mainly in adults and children. Accumulating evidence suggests that renal mesenchymal tumors represent a group of histologically heterogeneous diseases. We are reporting the case of a 58-year-old man with a history of nephron-sparing surgery due to renal cell carcinoma in 2014 in his left kidney.

Emphysematous pyelonephritis (EPN) and emphysematous cystitis (EC) are severe, necrotizing emphysematous urinary tract infections (EUTI) characterized by the presence of gas in the lumen and wall of the urinary tract and renal parenchyma. EUTIs are quite uncommon, but combination of bilateral EPN and EC is extremely rare. We report a case of 57-year-old diabetic female diagnosed with septic shock due to concurrent bilateral EPN and EC.

Introduction: Symptomatic hypermobile kidney is treated with nephropexy, a surgical procedure through which the floating kidney is fixed to the retroperitoneum. Although both open and endoscopic procedures have a high success rate, they can be associated with risk of complications, relatively long hospital stay and high cost.

Aim: We describe our percutaneous technique for fixing a hypermobile kidney and evaluate the efficacy of the percutaneous nephrostomy insertion in management of symptomatic nephroptosis.

A number of single nucleotide polymorphisms (SNPs) in the human genome have been associated with increased risk of prostate cancer. Recently, a single SNP in the region of chromosome 8q24 (rs188140481) has been associated with a three-fold increased risk of prostate cancer in Europe and North America. To establish whether rs188140481 is associated with the risk of prostate cancer in Poland, we genotyped 3467 men with prostate cancer and 1958 controls.

We shall discuss the case of a female patient, aged 64 years, who was suffering from long-term purulent inflammation of the vaginal fornix that later involved the vaginal stump. This inflammatory process spread to the bladder trigone and resulted in vesicovaginal fistula (VVF) formation together with a bilateral hydronephrosis that required the placement of a temporary percutaneous nephrostomy. A non-cicatrized inflammatory reaction occurred at the right-sided insertion of the nephrostomy, which has yet to be successfully treated despite intensive dermatological and surgical approaches that included skin grafting.

Article Synopsis
  • - The study investigated the Q548X mutation of the BLM gene in Polish men to see if it increases the risk of prostate cancer and affects survival rates.
  • - The mutation was found in a small percentage (0.4%) of prostate cancer patients, with no significant difference in survival rates between those with and without the mutation.
  • - The BLM Q548X mutation is common in Poland, but the research concluded it does not seem to predispose individuals to prostate cancer or influence survival outcomes.

Several single nucleotide polymorphisms (SNPs) have been associated with an elevated risk of prostate cancer risk. It is not established if they are useful in predicting the presence of prostate cancer at biopsy or if they can be used to define a low-risk group of men. In this study, 4,548 men underwent a prostate biopsy because of an elevated prostate specific antigen (PSA; ≥4 ng/mL) or an abnormal digital rectal examination (DRE).

Kidneys possess a complex enzyme system which plays a major role in tryptophan metabolism. Taking into account a considerably high concentration of one of the tryptophan metabolites, kynurenic acid (KYNA) in this organ and previously reported antiproliferative activity against colon cancer cells in vitro, we measured its content in human normal and tumour kidney tissue. KYNA concentration was considerably higher in normal renal tissue (379.

Evidence to date that BRCA1 mutation carriers are at an increased risk of prostate cancer is mixed - both positive and negative studies have been published. To establish whether or not inherited variation in BRCA1 influences prostate cancer risk we genotyped 1793 men with prostate cancer in Poland and 4570 controls for three founder mutations (C61G, 4153delA and 5382insC). A BRCA1 mutation was present in 0.
