DNA methylation makes up a main part of the molecular mechanism of cancer evolution and has shown promising results in the prognosis of renal cell cancer (RCC). In this study, we investigated the possible association of promoter methylation of PCDH17, NEFH, RASSF1A, and FHIT, genes with the prognosis of nonmetastatic RCC patients. Cancerous and normal adjacent tissues from surgical specimens of 41 patients with long follow-up were treated for DNA isolation and bisulfite conversion.

Although its role in other solid tumors, particularly renal cell carcinoma, has been sufficiently elucidated, it remains elusive in prostate cancer. The aim of the present study was to investigate the expression of main proteins involved in this pathway and determine the correlation of the results with clinicopathological outcomes of patients with prostate cancer.

However, there are currently no data regarding the behavior of this pathway (HIF/PHD) in a large number of benign renal tumors, the oncocytomas. The aim of the present study was to compare the expression levels of these factors between ccRCC and oncocytoma tumors.

Reverse transcription-quantitative PCR was used to quantify the mRNA expression levels of HIF-1α, HIF-2α, prolyl hydroxylase (PHD)1, PHD2 and PHD3 in formalin-fixed paraffin-embedded (FFPE) tumour tissue samples from 41 patients with RCC, including 33 cases of clear cell RCC (ccRCC). FFPE samples of corresponding adjacent normal kidney tissues were used as a comparison.

Immunohistochemical expression of Hypoxia inducible factors (HIF) HIF-1a, HIF-2a, prolyl hydroxylases PHD1, PHD2, PHD3, and factor inhibiting HIF (FIH) was assessed on a tissue microarray, containing tumour and corresponding normal kidney tissue from 66 patients underwent surgery for ccRCC. Expression levels were evaluated in relation to T stage, Fuhrman grade, cancer-specific, and overall survival (OS).

In urothelial cell carcinoma of the bladder, some reports have shown an association between HER-2 overexpression and worse outcomes. The aim of this study was to examine the association between HER-2 expression and other clinicopathologic parameters in 48 patients treated for primary non-muscle-invasive transitional cell carcinoma of the bladder.

A computerized search of PubMed and Scopus for articles published from inception through to January 2018 was performed including 24 studies with a total of 5173 patients. Even though different outcome measures require varying case-loads to reach a plateau, Holmium laser enucleation of prostate has an acceptable learning curve with a proposed figure approximating 25-50 cases, with a structured mentorship programme aiding for faster progress.

The exact pathogenesis is unknown, however more than 75% of cases are associated with renal stones. Here, we provide images from a case with 10 years of follow-up, outlining the radiographic progression of the disease through time.

However, the clinicians are often challenged with the decision whether to treat varicocele in patients with testicular pain or low testosterone levels. Moreover, varicocele is highly associated with DNA fragmentation due to the oxidative stress and it has been demonstrated that surgical repair of varicocele ameliorates oxidative stress markers and consequently the sperm DNA integrity.

In theory, the risk of prostatic fibrosis versus the potential benefit of reduced intraoperative bleeding has been addressed as potential competing factors. The aim of this review was to provide evidence whether 5α-reductase inhibitors (5-ARIs) put the surgeon at a disadvantage or impact on patient outcomes.

An intraperitoneal spread of mucus is the characteristic of the disease. Here, we provide images from a rare entity, a pseudomyxoma peritonei arising from urachal mucinous adenocarcinoma.

Methods: We evaluated 32 patients who underwent radical cystectomy and orthotopic Hautmann W neobladder with Abol-Enein-Ghoneim uretero-intestinal anastomosis for bladder cancer. The patients were initially examined by using both conventional and ambulatory UDS.
The aim of the study is to determine whether dermal scarification is equally effective for treating acute renal colic compared to diclofenac sodium intramuscular therapy. A prospective, randomized controlled study was conducted with methodologic rigor based on CONSORT criteria. A total of 291 patients, aged ≥ 18 years, suffering from acute renal colic were included in this trial and randomly assigned in two groups.

Aim: The primary goal was to evaluate patients' erectile function and patients' and their partners' satisfaction after IPP implantation. A secondary aim was to investigate potential determinative factors of satisfaction according to device characteristics, demographics, and cause of erectile dysfunction (ED).
Introduction: The presence of a mass in the epididymis is not a common entity. The papillary cystadenoma of epididymis is a benign tumor which may occur sporadically or as a characteristic of von Hippel-Lindau disease.
Presentation Of Case: We present a case of a 27-year-old man with a right scrotal mass who was treated with surgical excision.

UT usually is a transudative pleural effusion that presents in patients with obstructive uropathy and it may occur following surgical procedures in the ureter or kidney such as ESWL, PCNL, and URS. Its diagnosis requires a high degree of clinical suspicion since the respiratory symptoms tend to be absent or mild and the urological signs tend to dominate.

This can be accompanied with numerous troublesome long-term complications such as formation of stones, diverticula, and hairballs. We report two cases of men with a history of hypospadias repair being affected by such complications.

Urine usually moves into the pleural space from the retroperitoneal or peritoneal space via diaphragmatic lymphatics or an anatomical diaphragm defect. A total of approximately 70 cases have been previously described in the literature, and in the vast majority of cases urinothorax is unilateral and ipsilateral to the side of obstructive uropathy, trauma or malignancy.

When severe incontinence persists after the first postoperative year and conservative treatment has been failed, surgical treatment has to be considered. In these cases it is generally accepted that artificial urinary sphincter is the gold standard treatment.
