Efficacy of botulinum toxin in the management of refractory de novo overactive bladder symptoms in women after midurethral sling placement: retrospective, single center study.

Introduction: This study aimed o evaluate the efficacy of onabotulinumtoxin A (onaBTX-A) intradetrusor injections in women with refractory de novo overactive bladder (OAB) following midurethral sling (MUS) placement.

Material And Methods: A retrospective single-center study was conducted. We screened 372 women who underwent MUS surgery between August 2009 and January 2022.

Preservation of the native urethral plate and corpus spongiosum combined with buccal mucosa graft plus Orandi's penile skin flap as an alternative to staged urethroplasty for narrow penile strictures.

Objective: In narrow anterior urethral strictures, the combined buccal mucosa graft (BMG) with pedicled penile skin flap (PSF) represents a well-known effective alternative to staged urethroplasty. We hypothesized that if the native urethral plate and adjacent corpus spongiosum were preserved, a narrower flap would be needed, and reinforced ventral stability could be achieved without compromising the surgical outcome.

Methods: Twelve patients with narrow penile urethral strictures underwent single-stage augmentation urethroplasty using a combined technique.

Comparison of oral morbidity and mid-term efficacy of anterior urethroplasty using an autologous tissue-engineered graft (MukoCell®) versus native oral mucosa graft.

Objective: Our study aimed to compare surgical success rate (SR) and oral morbidity of augmentation urethroplasty for anterior urethral strictures using autologous tissue-engineered oral mucosa graft (TEOMG) named MukoCell® versus native oral mucosa graft (NOMG).

Methods: We conducted a single-institution observational study on patients undergoing TEOMG and NOMG urethroplasty for anterior urethral strictures >2 cm in length from January 2016 to July 2020. SR, oral morbidity, and potential risk factors of recurrence were compared between groups were analyzed.

Bilateral T-shaped Scrotoplasty as an Ancillary Technique of Staged Anterior Urethroplasty: The End Justifies the Means.

Staged urethroplasty is performed to treat long-segment obliterating anterior urethral strictures. The technique is particularly challenging when the penobulbar junction is involved, as it requires the transection of the scrotum and the formation of lateral testicular fans. To date, there is no established surgical protocol for this ancillary technique in large volume scrotums with excess skin.

Inhibition of Autophagy Potentiated Hippocampal Cell Death Induced by Endoplasmic Reticulum Stress and its Activation by Trehalose Failed to be Neuroprotective.

Introduction: Endoplasmic reticulum (ER) stress induced the mobilization of two protein breakdown routes, the proteasomal- and autophagy-associated degradation. During ERassociated degradation, unfolded ER proteins are translocated to the cytosol where they are cleaved by the proteasome. When the accumulation of misfolded or unfolded proteins excels the ER capacity, autophagy can be activated in order to undertake the degradative machinery and to attenuate the ER stress.
