Aims: Analysis and description of the supporting fascial structure around the prostate and urethra, which needs to be preserved or restored during radical prostatectomy (RP).
Methods: Anatomical dissection of 10 male cadavers was performed and the supporting fascial structures of bladder neck, prostate, and proximal urethra were investigated. The cadavers were embalmed according to Thiel's method, which preserves a natural texture and color of tissues.
Results: Anteriorly, the puboprostatic ligament (PL), the dorsal vein complex, and the urethropelvic ligament form an integral structure that suspends and stabilizes the prostatic apex. Laterally, the fascia originates from the fascial tendinous arch of the pelvis and stabilizes the prostate in the central position. In the posterolateral aspect, we could demonstrate a tendineous dorsal raphe, which represents an important stabilization structure of the urethra.
Conclusions: The anterior and posterior pelvic fascial structure seems to be important stabilizer for the prostate and proximal urethra. Their preservation or reconstruction during RP is mandatory to restore the anatomic and functional continuity of the bladder neck and urethra. Neurourol.

Prune belly syndrome (PBS), or Eagle-Barrett syndrome, is a rare congenital disorder marked by abdominal wall muscle deficiency, urinary tract anomalies, and cryptorchidism, causing significant abdominal wall laxity and functional impairment. This case report discusses an innovative approach to abdominal wall reconstruction in a 19-year-old male patient with PBS and associated conditions, including chronic renal failure and spina bifida. Previously, he underwent distal ureterectomy and vesicoureteral reimplantation at the age of two years to correct urinary tract dilation and bilateral orchiopexy.

Necrotizing soft tissue infections (NTSIs) represent a concept of necrotizing infections involving the skin, subcutaneous tissue, fascia, and muscle, and it is a potentially fatal disease. Early exploratory incision is strongly recommended for both the diagnosis and treatment of necrotizing soft tissue infections. Treatment of necrotizing soft tissue infections requires the administration of appropriate antimicrobial agents and adequate surgical debridement.

Obesity is a complex and non-communicable disease with a pandemic entity. Currently, multiple causes can lead to obesity, and it is not always easy to create a direct relationship between physical inactivity, poor quality of nutrients consumed, and calculation of excess calories. Among the associated comorbidities, obesity creates a dysfunctional environment of respiratory rhythms at the central and peripheral levels, with functional, morphological, and phenotypic alteration of the diaphragm muscle.

Cervical subcutaneous emphysema and pneumomediastinum without pneumothorax are exceedingly rare complications following rhinoplasty, with limited cases reported in the literature. This report presents a case of revision septorhinoplasty using autologous costal cartilage, where the patient complained of a sore throat 36 hours postoperatively. On physical examination, cervical subcutaneous emphysema was palpated, and radiologic evaluation confirmed both cervical subcutaneous emphysema and pneumomediastinum.

Background: One of the common complications in spinal surgery patients is deep surgical site infections (SSIs). Deep SSIs refer to infections that involve the deeper soft tissues of the incision, such as the fascia and muscle layers. This complication can lead to prolonged hospitalization, repeated surgeries, and even life-threatening conditions.
