We aimed to evaluate the feasibility and long‐term functional outcomes of surgical correction of adult buried penis patients due to complications of childhood circumcision. A retrospective analysis was performed for patients who underwent treatment for buried penis between 1997 and 2019. An autologous split‐thickness skin graft (STSG) was used. Surgical management steps included circumcision, resection of the bands between the corpora and other tissues, harvesting of STSG from femoral region and graft application. Surgical and functional outcomes were the primary end points. Thirteen patients were included with a mean age of 22.4 years and median body mass index 27. Patients had similar symptoms, including sexual dysfunction, inadequate penile length, impossible penetration and decreased quality of life. No early post‐operative complication was seen. During a median of 44‐month follow‐up, post‐operative long‐term complications were seen in 4 (30%) patients: decreased graft sensation (n = 2); graft contracture five months after surgery (n = 1); and retarded ejaculation (n = 1). Patients’ post‐operative three‐month International Index of Erectile Function (IIEF) score and sexual satisfaction score (SSS) significantly increased compared with patients’ pre‐operative scores (IIEF; 22.8 vs. 14.1, p = .03, SSS; 8.7 vs. 3.2, p < .01). Buried penis is a rare but challenging condition. Patients had excellent graft acceptance with successful functional outcomes.

Retroperitoneal haematoma is a rare clinical entity with variable etiology. It can happen spontaneously, without any obvious precipitating factors, the so-called spontaneous retroperitoneal haematoma. There is no general consensus as to the best management plan for patients with retroperitoneal haematoma. Polyarteritis nodosa (PAN) is a rare cause of retroperitoneal haematoma. Here we report relationship between PAN and retroperitoneal haematoma and treatment approaches. However, an accepted and clearly defined treatment has not been established due to its rarity.

Objective: Only a few papers in the literature aimed to evaluate biopsy core lengths. Additionally, studies evaluated the core length with different approaches. We aimed to determine whether prostate cancer (PCa) detection is affected from core lengths according to three different approaches in a large standard cohort and compare our cut-off values with the published cut-offs. Material and methods:We retrospectively analyzed 1,523 initial consecutive transrectal ultrasound-guided 12-core prostate biopsies. Biopsies were evaluated with respect to total core length (total length of each patients' core) average core length (total core length divided by total number of cores in each patient), and mean core length (mean length of all cores pooled), and compared our cut-off values with the published cut-offs. The prostate volumes were categorized into four groups (<30, 30-59.99, 60-119.99, ≥120 cm 3 ) and PCa detection rates in these categories were examined.Results: PCa was found in 41.5% patients. There was no difference between benign and malignant mean core lengths of the pooled cores (p>0.05). Total core length and average core length were not significantly associated with PCa in multivariate logistic regression analyses (p>0.05). The core lengths (mean, average and total core lengths) increased (p<0.001) and PCa rates decreased (p<0.001) steadily with increasing prostate volume categories. PCa percentages decreased in all categories above the utilized cut-offs for mean (p>0.05), average (p<0.05), and total core lengths (p>0.05). Conclusion:There was no difference between mean core lengths of benign and malignant cores. Total core length and average core length were not significantly associated with PCa. Contrary to the cut-offs used for mean and average core lengths in the published studies, PCa rates decrease as these core lengths increase. Larger studies are necessary for the determination and acceptance of accurate cut-offs.

Although intravesical ALS treatment has similar antiproliferative effects like BCG, ALS + BCG combined treatment led to a best histopathologic and apoptotic response. Consequently, BCG combined with Aurora-A inhibition may provide a new intravesical treatment modality in the prevention of bladder carcinogenesis.

Intravesical Bacillus Calmette-Guerin (BCG) is the best treatment modality for progression of non-muscle invasive bladder cancer. We aimed to monitor changes at the proteome level to identify putative protein biomarkers associated with the response of urothelial precancerous lesions to intravesical BCG treatment. The rats were divided into three groups (n = 10/group): control, non-treated, and BCG-treated groups. The non-treated and BCG-treated groups received N-methyl-N-nitrosourea intravesically. BCG Tice-strain was instilled into bladder in BCG-treated group. At the endpoint of experiment, all surviving rat bladders were collected and equally divided into two portions vertically from dome to neck. Half of each bladder was assessed immunohistopathologically and the other half was used for 2D-based comparative proteomic analysis. Differentially expressed proteins were validated by Western blot analysis. Precancerous lesions of bladder cancer were more common in non-treated group (77.8%) than in BCG-treated group (50%) and the control group (0%). Greater than twofold changes occurred in the expression of a number of proteins. Among them, Rab-GDIβ, aldehyde dehydrogenase 2 (ALDH2) and 14-3-3 zeta/delta were important since they were previously reported to be associated with cancer and their expression levels were found to be lower in BCG-treated group in comparison to the non-treated group. ALDH2 and 14-3-3 zeta/delta were also found to be highly expressed in the non-treated group compared to the control group. The down-regulation of these proteins and Rab-GDIβ was achieved with BCG; this result indicates that they may be used as putative biomarkers for monitoring changes in bladder carcinogenesis in response to BCG immunotherapy.

Objective: To evaluate the impact of Double J stent (DJS) insertion during open partial nephrectomy (OPN) on postoperative prolonged urinary leakage. Materials and methods: A retrospective study was made in consecutive cases of OPN performed between 2002 and 2020 for localized kidney tumors at our tertiary center. Urinary leakage was defined as drainage > 72 hours after surgery by biochemical analysis consistent with urine or radiographic evidence of urine leakage. The patients were divided into two groups according to intraoperative DJS placement, and compared regarding clinicopathologic characteristics, perioperative and postoperative outcomes. Univariate and multivariate logistic regression analyses were performed to determine the factors associated with urinary leakage after the operation. Results: Review of records identified 182 patients who were included in the study. In 73 (40%) patients PN was performed without insertion of a DJS. Thus, 109 (60%) of patients had a DJS inserted. Apart from higher preoperative eGFR values among patients with DJS (96.6 vs. 94.3 mL/min/1.73 m²; p = 0.03), demographic characteristics were similar between groups. The two groups were not different regarding perioperative, postoperative and clinicopathologic outcomes. Patients with DJS had longer ischemia times (31 vs. 23 min; p = 0.02) and longer length of stay (6 vs. 5 days; p = 0.04). Urinary leakage was seen in 7.6% (n = 14) of all patients and it did not differ according to DJS placement (DJS+ 9.2 vs. DJS- 5.5%; p = 0.41). On multivariate analysis, the tumor nearness to the collecting system was the sole independently significant factor (p = 0.04) predicting postoperative urine leak. Conclusions: Routine intraoperative DJS insertion during OPN does not appear to reduce the probability of postoperative urine leak.
