• According to our analysis of prospectively collected data, PSAD may be a significantly more accurate preoperative predictor of upgrading than PSA, even when accounting for detailed biopsy core data in the current era of extended prostate biopsies. • Our findings would support the inclusion of PSAD, rather than PSA, into the risk stratification system for patients seeking less invasive treatment for prostate cancer.

The longer exposure duration of electromagnetic field decreased the spermatogenesis. Our findings warrant further investigations on the potential effects of EMF from mobile phones on male fertility.

Partial nephrectomy provides similar recurrence-free survival outcomes compared with radical nephrectomy in patients with clinical T1a pathological T3a renal cell carcinoma. However, there seems to be a higher risk of recurrence for large pathological T3a tumors treated by radical nephrectomy compared with small tumors treated by partial nephrectomy. Thus, large tumors with the same pathological T3a renal cell carcinoma grade could have hidden aggressive features.

The accuracy of PSA in predicting prostate cancer did not change regardless of BMI category in Asian men. However, as patients with higher BMIs had lower PSA levels than those with lower BMIs, it can therefore be suggested that the PSA threshold should be lower in obese men to discriminate between prostate cancer and benign conditions in the real clinical situation.

RPN may result in a narrower peritumoral surgical margin than OPN. Further investigation on the potential impact of such a phenomenon should be performed in a larger-scale study.

Considering the perioperative and postoperative parameters, RPN is a viable option as a nephron-sparing surgical procedure for small renal masses that yields outcomes comparable to those achieved with OPN. Despite matched cohort analysis among patients who underwent PN by a single surgeon, there may be inherent selection bias; therefore future prospective trials are needed.

The personalized extracorporeal biofeedback device for PFMT offers a significant positive effect on the recovery of PPI after RARP, especially in the early postoperative period. Furthermore, patients can be offered more convenience through performing the regular exercise at any place with ease.

Patients who attained the RARC pentafecta had significantly better survival outcomes compared with those who did not. These criteria could be used to standardize assessment of the surgical quality of RARC. In the future, a similar study using an independent cohort is warranted to confirm our results.

The administration of cephalosporin-based prophylactic antibiotics and the simple use of suppository-type povidone-iodine provided an excellent protocol for reducing infective complications of TRUS-guided prostate biopsy. The simplicity of use and cost effectiveness of gynobetadine were noteworthy.

<b>Background:</b> Preoperative hydronephrosis (HN) might be associated with adverse outcomes in patients who underwent radical cystectomy (RC). The aim of this study was to evaluate the effect of preoperative HN on the oncological outcomes in patients with bladder cancer who underwent RC by performing a systemic review and meta-analysis. <b>Methods:</b> A systematic literature review in PubMed, EMBASE, and Scopus was conducted by searching the terms "bladder cancer," "cystectomy," and "hydronep

The pathological stage, PSM, and PLM were significantly associated with the survival of UC patients, emphasizing an importance of the complete surgical resection of tumor lesion.

Among bladder cancer patients who underwent radical cystectomy, the diabetes mellitus patients had worse cancer-specific mortality and overall mortality outcomes than the non-diabetes mellitus patients. The mechanism of association between diabetes mellitus and urothelial bladder cancer should be investigated to validate the present results in a future prospective study.
