Strictures involving the penile urethra generally require tissue transfer techniques. Ventral graft placement usually is avoided in the penile urethra because of the relative paucity of viable corpus spongiosal tissue necessary for vascularization and support. Instead, grafts are commonly placed dorsally using either an onlay or inlay technique. However, the successful use of ventrally placed grafts in the penile urethra supported by a pseudospongioplasty has recently been reported. The incorporation of a pseudospongioplasty provides a well-vascularized milieu for successful graft take in the penile urethra. This technique incorporates periurethral flaps of tunica dartos and Buck's fascia for graft coverage. Pseudospongioplasty in the penile urethra has been shown to have a similar efficacy to standard spongioplasty in the bulbar urethra. Additionally, pseudospongioplasty outcomes are comparable to other graft augmentation techniques performed in the penile urethra. In penile strictures, where there is a paucity of spongiosal tissue, pseudospongioplasty for coverage of a ventral graft is a reliable option.

Introduction: The presence of foreign or unexpected external objects in the urinary tract, including the urethra, is a rare case. This case is a challenge for patients with schizophrenia. This case report presents when the unusual corpus alienum invades the urethra in schizophrenia patients.

Urinary tract injuries represent a significant clinical challenge, necessitating precise diagnosis and effective treatment strategies. Rat models are preferred for studying urinary tract injuries due to their size, visibility of external genitalia, and robust reproductive and growth capabilities. However, there is a lack of standardized methodologies for evaluating the endpoints of rat urinary tract injury models.

Angiosarcoma of the penis is an exceptionally rare mesenchymal tumor, with only about 30 cases documented in the literature. Because of its rarity and the often nonspecific clinical presentation, histopathological examination plays a critical role in accurate diagnosis. Angiosarcoma of the penis typically arises in the corpus cavernosum but has also been reported in the glans and urethra, often presenting with metastases.

Introduction: Ideal treatment of lichen sclerosus (LS) induced penile urethral strictures (PUS) remains elusive. The objective of this study is to compare multi-institutional outcomes of single-stage urethroplasty (SSU) with oral mucosal graft (OMG), staged urethroplasty and perineal urethrostomy (PU) for treatment of LS induced PUS.
Methods: Multi-institutional analysis was performed at 9 centers on males undergoing SSU, staged urethroplasty or PU for LS induced PUS.

Purpose: To determine the clinical effects of urethral suspension-assisted urethral anastomosis on complex long-segment posterior urethral stricture and describe the technical aspects of this procedure.
Materials And Methods: The clinical data for 24 patients who underwent urethral suspension-assisted urethral anastomosis for complex long-segment posterior urethral stricture between March 2021 and March 2024 were retrospectively analyzed. The surgical procedure comprises the following four steps: creation of an inverted Y-shaped incision in the perineum; mobilization of the urethra up to the penile-scrotal junction followed by dissection and separation of the septum of the corpus cavernosum; separation of the inferior pubic symphysis, excising a portion of the inferior pubic symphysis bone tissue and thoroughly clearing the scar tissue surrounding the proximal urethra; and suturing and suspension of the proximal urethra and surrounding tissues at the 2, 5, 7, and 10 o'clock positions, ensuring complete exposure of the proximal urethral mucosa and tension-free anastomosis between the proximal and distal urethra.
