Analysis of Patients with Urethral Stricture in Kidney Transplant Recipients.

Background: We aimed to assess the rates of urethral stricture in transplant recipients, analyse patients with urethral strictures and present the posttreatment follow-up outcomes.

Methods: Between 2004 and 2023, a retrospective examination was conducted on kidney transplant recipients who underwent removal of ureteral catheters through retrograde cystoscopy at our facility or referred from external centres.

Preoperative multiparametric magnetic resonance imaging based risk stratification system for predicting biochemical recurrence after radical prostatectomy.

Background: Multiparametric magnetic resonance imaging (mpMRI) is used as a current marker in preoperative staging and surgical decision-making, but current evidence on predicting post-surgical oncological outcomes based on preoperative mpMRI findings is limited. In this study We aimed to develop a risk classification based on mpMRI and mpMRI-derived biopsy findings to predict early biochemical recurrence (BCR) after radical prostatectomy.

Methods: Between January 2017 and January 2023, the data of 289 patients who underwent mpMRI, transrectal ultrasound-guided cognitive and fusion targeted biopsies, and subsequent radical prostatectomy (RP) with or without pelvic lymph node dissection in a single center were retrospectively re-evaluated.

Monocular transcorneal electrical stimulation induces ciliary muscle thickening in contralateral eye.

Transcorneal electrical stimulation (TES) is used as therapy for retinal diseases such as retinitis pigmentosa (RP) and was suggested for assessing retinal sensitivity by determining phosphene thresholds, subjective luminance impressions caused by retinal stimulation. Further applications concerned the accommodation process, revealing an improved accommodative amplitude in presbyopic eyes after TES treatment. The respective changes of the ciliary muscle (CM), the structure most important for near vision, during TES are yet unknown.
