Substitution Urethroplasty With Buccal Mucosal Graft in the Management of Stricture of Vesicourethral Anastomosis or Membranous Urethra: Single-institution Long-term Experience With Perineal Approach and Endourethroplasty.

Objective: To present long-term experience with buccal mucosa posterior urethroplasty (BMPU) for refractory posterior urethral stenosis (PUS) or vesicourethral anastomosis stenosis (VUAS) either by perineal approach (PA) or by endourethroplasty (EUP).

Materials And Methods: A single-center retrospective study of 38 consecutive patients operated on between 1999 and 2022. BMPU consisted of the transfer of onlay or tubular buccal mucosa grafts into dilated and/or incised strictures through an open or endourological approach.

Oncological outcomes of surgery for isolated retroperitoneal recurrence in renal cancer patients after radical nephrectomy.

Aims: Isolated retroperitoneal recurrence (IRR) in renal cancer patients after radical nephrectomy (RN) is a rare event and poses a therapeutic dilemma. We evaluated oncologic outcomes in surgically treated patients with IRR and established prognostic factors associated with survival. The benefit of metastasis-directed therapy (MDT) in those with clinical progression after extirpation of IRR was assessed.

Comparison of Different Treatment Modalities Outcomes in Clinically Node-positive Bladder Cancer: Analysis of a Population-based Cancer Registry.

Introduction: Patients with clinically node-positive bladder cancer were historically considered to have uniformly poor prognosis and were frequently treated with palliative chemotherapy (CHT) only. Although retrospective data show that long-term survival with combined treatment (surgery + CHT) is possible in one-third of these patients, consensus on a treatment algorithm is still lacking. The aim of the study is to compare the efficacy of different treatment modalities based on data from a population-based cancer registry.

Sentinel lymph node dissection combined with meticulous histology increases the detection rate of nodal metastases in prostate cancer.

Purpose: To evaluate benefits of sentinel lymph node (SLN) biopsy for staging accuracy in prostate cancer. Extended pelvic lymph node dissection (ePLND) is a preferred staging tool; however, it may underestimate the incidence of nodal involvement.

Methods: Eighty patients with estimated risk of lymphadenopathy above 5 % based on Briganti nomogram had Tc-99m-labeled nanocolloid injected into the prostate.

Effect of ureterointestinal anastomosis on renal function and morbidity in intestinal urinary diversion.

Objective: The authors previously successfully applied the "flap-and-trough" (FT) method of antireflux ureterointestinal anastomosis (UIA) in a pilot set of 81 patients. This randomized prospective trial tested the effectiveness of this method in protecting the upper urinary tract from obstruction, reflux and infections.

Material And Methods: Forty-nine patients indicated for cystectomy and intestinal urinary diversion were randomly split into two groups, A and B.

HLA-G and HLA-E specific mRNAs connote opposite prognostic significance in renal cell carcinoma.

Background: Renal cell carcinoma (RCC) is characterized by its resistance to radiotherapy and/or chemotherapy. On the other hand, it is an immunogenic tumor - it is able to stimulate antitumor responses. A prognostic significance of HLA-G expression by neoplastic cells in RCC is not well characterized; significance HLA-E expression in RCC is not characterized at all.
