Exploring the contribution of joint angles and sEMG signals on joint torque prediction accuracy using LSTM-based deep learning techniques.

Machine learning (ML) has been used to predict lower extremity joint torques from joint angles and surface electromyography (sEMG) signals. This study trained three bidirectional Long Short-Term Memory (LSTM) models, which utilize joint angle, sEMG, and combined modalities as inputs, using a publicly accessible dataset to estimate joint torques during normal walking and assessed the performance of models, that used specific inputs independently plus the accuracy of the joint-specific torque prediction. The performance of each model was evaluated using normalized root mean square error (nRMSE) and Pearson correlation coefficient (PCC).

Laser enucleation for prostates larger than 100 mL: Comparison of HoLEP and ThuLEP.

Recently, with the advancements in laser technology, Holmium laser enucleation of the prostate (HoLEP) and Thulium laser enucleation of the prostate (ThuLEP) have come to the fore in the surgical treatment of benign prostatic hyperplasia (BPH). We aimed to evaluate and compare the outcomes of HoLEP and ThuLEP in patients with >100 ml prostate volume. Patients who underwent HoLEP and ThuLEP between July 2017 and March 2020 were reviewed retrospectively.

Evaluation of static and dynamic Pupillometry changes in men using Silodosin for benign prostatic hypertrophy.

Background: Intraoperative floppy iris syndrome is a variant of the small pupil syndrome that has been observed during cataract surgery in some patients currently or previously treated with α1 adrenergic blockers. It is important for cataract surgeons to predict the probable complications preoperatively. Our study aims to evaluate the static and dynamic pupil characteristics of patients treated with silodosin-a selective α1 adrenergic blocker-for benign prostate hypertrophy (BPH) and to compare these values with healthy subjects using an automatic quantitative pupillometry system.

Renal autotransplantation due to iatrogenic ureter injury: A case report.

Hardy and colleagues carried out 'Renal autotransplantation' for the first time in 1963 to treat severe ureter injury and it has evolved as a method used for complex treatment of trauma, renal artery diseases or ureteral stenosis. In case of proximal ureter injury, approximately 2/3 of which is iatrogenic, if the end-to-end anastomosis is not possible, renal autotransplantation, ileal ureter interposition or nephrectomy are alternative treatments. As technology advances, the use of ureterorenoscopy (URS) increases and in parallel with this iatrogenic injuries that occur during the process have increased as well.

The effects of bladder neck sparing with an additional anterior urethral fixation on postoperative continence after robot-assisted radical prostatectomy.

Objective: Urinary incontinence remains one of the main problems affecting the quality of life after radical prostatectomy. Along with the improved understanding of the precise anatomy of the prostate, urethra and their surrounding structures, minimally invasive surgical techniques have been refined and described, aiming to improve functional outcomes without oncological compromise. This study aimed to investigate the impacts of anterior urethral fixation (AUF) and bladder neck sparing (BNS) on the early continence success after Robot-assisted Radical Prostatectomy (RALP).

Comparison of outcomes of Holmium enucleation of the prostate for small- and moderate-sized prostates.

There is an ongoing discussion in the literature on the surgical treatment option for small prostate size benign prostate hyperplasia (BPH) patients. This study aimed to evaluate the efficacy of Holmium laser enucleation of the prostate (HoLEP) surgery in small (<30 ml) and moderate (30-80 ml) prostate size as accepted in European Association of Urology guideline. We retrospectively analysed our database between May 2016 and May 2019 and patients who underwent HoLEP surgery.

HoLEP after prostate biopsy: does it have any impact?

Purpose: Holmium laser enucleation of the prostate (HoLEP) has recently become the recommended treatment for prostate in all sizes in benign prostate hyperplasia surgery. A recent prostate biopsy performed prior to the HoLEP procedure can make surgeons concerned about the surgery. We aimed to investigate the per- and postoperative outcomes of the HoLEP procedure in patients who underwent prostate biopsy and to evaluate the most appropriate surgery time after biopsy.

The "Omega Sign": a novel HoLEP technique that improves continence outcomes after enucleation.

Purpose: Holmium-laser enucleation of the prostate (HoLEP) has been a promising prostate surgery since its first introduction. Although there are 10 different HoLEP techniques in the literature, stress urinary incontinence (SUI) is common, because surgery is not performed based on the topographic anatomy of the external sphincter. We have developed a new HoLEP method named as the ''Omega Sign technique", which is based on the topographic anatomy of the external sphincter and could provide better continence outcomes by decreasing SUI rates.
