Ambulatory autoinjection therapy of the corpus cavernosum with a vasoactive drug combination for vasculogenic and neurogenic erectile dysfunction was performed in 50 men from 10/85-6/87. Acceptance was excellent by all patients and their wives. Transitory hematomas appeared in 6/50 (12%) cases. Local infections, cavernitis or systemic side effects were not observed. In 3/50 (6%) patients prolonged erections occurred. Treatment included drainage of the intracavernous blood, manual decompression and if necessary additional application of 1 mg metaraminol under extreme caution. Only 1 (2%) patient developed a nodular tunica fibrosis at the injection site which disappeared spontaneously upon cessation of treatment within 4 weeks.

hUC-MSC preserves erectile function by restoring mitochondrial mass of penile smooth muscle cells in a rat model of cavernous nerve injury via SIRT1/PGC-1a/TFAM signaling.

Background: Cavernous nerve injury-induced erectile dysfunction (CNI-ED) is a common complication following radical prostatectomy and severely affects patients' quality of life. The mitochondrial impairment in corpus cavernosum smooth muscle cells (CCSMCs) may be an important pathological mechanism of CNI-ED. Previous studies have shown that transplantation of human adipose derived stem cells (ADSC) can alleviate CNI-ED in a rat model.

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.

Background: Pelvic trauma can have long-lasting debilitating effects, including severe erectile dysfunction (ED) in men. While there are effective treatments for ED, these treat the symptoms not the cause. Those who suffer from an acute traumatic injury to the neurovascular supply of penis, may benefit from regenerative therapy.

Adrenergic stimulation induces contractions in the corpus cavernosum smooth muscle (CCSM) that are important in maintaining penile flaccidity. The aim of this study was to investigate the role of K7 channels in regulating contractions and their underlying Ca signals in mouse CCSM. Quantitative PCR revealed transcriptional expression of KCNQ1 and KCNQ3-5 genes in whole CCSM, with KCNQ5 as the most highly transcribed K7 encoding gene.

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.
