Background: Several factors such as recipient age, BMI, serum cratinine, and positive history of dialysis are important in predicting graft survival among kidney transplant recipients. One factor affecting the transplant outcomes is donors and recipients gender, which is usually ignored.Methods: A total of 1113 kidney transplant recipients were studied in this retrospective cohort study. Several factors were taken into account for graft survival and outcomes such as donors and recipients gender and age in addition to common recipient factors like cratinine, eGFR, BMI, and positive history of dialysis.Results: The most successful transplant based on donor-recipient gender was observed in male donor to male recipient, and then male donor to female recipient. In female transplant recipients, level of serum cratinine and eGFR, positive dialysis history before transplant, and low donor hemoglobin level can be considered as good prognostic factors recommended for kidney transplant survival.Conclusions: Our results suggested gender matching for kidney transplant. Only in some exceptional conditions, male donor to female recipient kidney transplant may be successful and female donors to male recipients are not suggested, especially in aged patients with the history of dialysis.

Purpose: Percutaneous nephrolithotomy is generally performed using fluoroscopy, which is associated with exposure to radiation. Another drawback of fluoroscopic guided percutaneous nephrolithotomy is the prone position, which is not suitable for all patients. In this study we evaluated the feasibility, safety and efficacy of ultrasound guided percutaneous nephrolithotomy with the patient in the flank position. Materials and Methods: A total of 603 patients with a mean +/- SD age of 50.9 +/- 13 years were included in this study from December 2010 to July 2016. Access to the collecting system and tract dilation were performed under ultrasound guidance. Perioperative data on the stone-free rate, operative time, length of stay and complication rates were recorded. Results: Successful access was achieved in all but 1 patient. Mean operative time was 56.6 +/- 6.5 minutes. Complete stone clearance was achieved in 529 patients (87.7%) and Clavien-Dindo grade 3 complications were noted in 17 (2.8%). Blood transfusion was necessary in 43 patients (7.1%). However, bleeding was self-limited in all cases and did not require angioembolization. Conclusions: To our knowledge this is the largest series of ultrasound guided percutaneous nephrolithotomy with the patient in the flank position. Unlike in other studies we used this procedure in all patients irrespective of stone burden, renal anomaly and body habitus. Ultrasound guided percutaneous nephrolithotomy has outcomes comparable to those of conventional percutaneous nephrolithotomy and it is not associated with radiation exposure. Furthermore, anesthesia while in the flank position might be less harmful in some patients, including those with obesity or cardiopulmonary comorbidities.

Background: Transitional cell carcinoma (TCC) of the bladder is the second most common genitourinary malignancy. Because of the low sensitivity of urinary cytology and the invasiveness and expense of frequent cystoscopies for the detection of low-grade superficial lesions, we aim to establish a sensitive molecular approach to detect bladder cancer noninvasively. Methods: Voided urine samples were collected from 80 patients with bladder cancer at the time of diagnosis, in addition to 30 patients with non-bladder cancer urological diseases and 20 healthy volunteers. The level of hTERT, KRT7, and survivin (SVV) mRNAs were analyzed using a qRT-PCR assay. Results: The optimal threshold values for hTERT, KRT7, and SVV in urine were calculated by ROC curves analysis. The overall sensitivity was 81.3%, 91.3%, and 68.8% for hTERT, KRT7, and SVV, respectively, which were significantly higher than urine cytology (22.2%, p < 0.001). A higher positive ratio was obtained using multi-marker detection in comparison to single marker detection. The combined use of markers increased the sensitivity of cytology from 22.2 to 100%. In contrast with the urine cytology method, the sensitivity of these biomarkers was not correlated with the grades and stages of the bladder tumors. Conclusions: Our data indicate that urinary hTERT, KRT7, and SVV have superior sensitivities over cytology. The combined use of these markers offers a powerful potential assay and promising tool for a sensitive, noninvasive, and highly specific diagnostic method and follow-up of low-grade TCC of the bladder.

The aim of this study was to evaluate and compare the efficiencies of unilateral and bilateral vasovasostomies as the vasectomy reversal procedures. A total of 95 patients with a history of bilateral vasectomy were evaluated. 42 of them had undergone unilateral surgery, and bilateral surgery had been done for the other 53 patients. Their information including the age, the time interval between the initial vasectomy to the reversal surgery and other underlying illnesses or medications was gathered. Patency rates in the unilateral and bilateral groups were 88.1% (38 patients) and 88.7% (48 patients), respectively, the difference of which was not statistically significant (p = .907). Successful pregnancies occurred in 22 (52.4%) and 29 (54.7%) patients, respectively, which did not show any statistically significant difference too (p = .713). Based on the multivariate logistic regression model, only the time interval between vasectomy and the reversal (duration of obstruction) was predictive of patency (OR = 1.112, p = .037). The outcomes of the unilateral and bilateral vasovasostomies in terms of patency and pregnancy rates were not significantly different. We suggest that performing unilateral, instead of bilateral, vasovasostomy can reduce the time of anaesthesia and surgery and save costs and consumables without having a significant negative impact on the surgical outcomes.

We describe an extremely rare case of Phyllodes tumor of the prostate in a 35-year-old man. The patient was referred to our hospital for the recurrent episodes of urinary retention. He complained of severe obstructive lower urinary tract symptoms and dysuria. Serum prostate-specific antigen (PSA) was within the normal range. Transabdominal ultrasonography showed a few heterogenous echoic areas in a 110-gm prostate and some cystic areas with invasion to the urinary bladder. In the past, transurethral resections of the prostate (TURP) had been performed for him twice and microscopic examination of the specimens had shown cystically dilated glands consisting of bizarre cells with nuclear atypia. Finally, radical retropubic prostatectomy was performed against the recurrences of the tumor. Here we describe the morphological features and immuno-histochemical presentations of Phyllodes tumor of the prostate and its long-term follow-up in the patient.
