Transvaginal Polytetrafluoroethylene Mesh Surgery for Pelvic Organ Prolapse: One-Year Safety and Efficacy Results.

Objective: To evaluate the efficacy and safety of the polytetrafluoroethylene (PTFE) mesh by comparing conventionally used polypropylene (PP) mesh in tension-free vaginal mesh (TVM) surgery for pelvic organ prolapse (POP).

Methods: We conducted an observational cohort study of patients who underwent TVM using a PTFE or PP mesh. PTFE was used from June 2019 to May 2021, and PP mesh from January 2018 to May 2019.

[Percutaneous Nephrolithotripsy for Renal Transplant Lithiasis: A Case Report].

A 54-year-old man was introduced to our hospital for follow-up examinations after renal transplantation. At the initial visit, a 25 mm renal transplant stone was noted, which had enlarged to 32 mm at an examination 1 year later. We first attempted transurethral lithotripsy (TUL), but failed due to ureteral stricture.

[Successful treatment of spontaneous rupture of pheochromocytoma with laparoscopic adrenalectomy: a case report].

A 46-year-old man had sudden onset of severe left hypochondrial pain and went into shock following hospitalization. Computed tomography, echocardiography, and endocrinological tests revealed spontaneous rupture of a pheochromocytoma associated with catecholamine cardiomyopathy. After he underwent conservative management with fluid replacement, his blood pressure stabilized and cardiac function improved.

[Poor outcome due to spontaneous rupture of renal cell carcinoma : a case report].

A 54-year-old man experienced sudden onset of severe pain in his left lower back. Because the pain persisted for two days, he visited our hospital. Abdominal computed tomography revealed a hematoma around his left kidney, which was diagnosed as spontaneous rupture of a renal tumor.

[Endocervicosis/endosalpingiosis of the bladder: a case report].

Endocervicosis/ endosalpingiosis of the bladder is a very rare benign condition, with a total of 34 documented cases found in the literature. Herein, we report a 35-year-old woman with suspected bladder cancer following a cystoscopic examination, which revealed a mass on the right posterior bladder wall. Transurethral resection of the lesion was performed, and both pathological and immunohistochemical findings confirmed a diagnosis of endocervicosis/ endosalpingiosis.

[IgG4-related idiopathic segmental ureteritis which was difficult to distinguish from ureteral cancer: a case report].

A 79-year-old woman was admitted with a chief complaint of gross hematuria, pollakisuria, lower abdominal pain. Urine cytology, intravenous pyelography, and cystoscopy were performed but showed no abnormal findings. About 6 months later, abdominal computed tomography (CT) revealed a 5cm long segment of ureteral narrowing with wall thickening, hydronephrosis, para-aortic lymph node swelling.

[A case of chemical burn of the penis].

A chemical burn is not so common in the urological field. In addition, a chemical burn of the penis is quite rare. We experienced a case of chemical burn of the penis caused by resin for making fiber-glass reinforced plastics (FRP).

[Three cases of penile self-mutilation].

Penile self-mutilation is rare. We report our experience with 3 cases of penile self-amputation. One case was in a 48-year-old man who had no background history of mental disorders.

[A case of solitary epididymis rupture after blunt scrotal trauma].

Blunt trauma of the scrotum is sometimes associated with severe injuries such as testis rupture. However, there are few reports of traumatic rupture of the epididymis with blunt scrotal trauma. In addition, severe epididymis injuries after scrotal trauma are always associated with severe testis trauma.

[Successful testicular sperm extraction in a non-obstructive azoospermic man with severe testicular microlithiasis : a case report].

A 45-year-old man was referred to our hospital for treatment of azoospermia. On physical examination, right testicular volume was 2 ml, left testicular volume was 3 ml, and pubic Tanner stage was 5. Scrotal ultrasonography revealed a high echoic lesion with acoustic shadowing at surfaces of bilateral testes.

[Excellent growth following testosterone replacement therapy in identical twin with bilateral anorchia].

Bilateral anorchia is defined as the complete absence of testicular tissue with a normal male karyotype and phenotype. Although the precise etiology is not well understood, mechanical causes during or after testicular descent have been suggested, while genetic factors have also been reported. We treated a patient with bilateral anorchia who obtained excellent growth bytestosterone replacement therapyas compared with his normal identical twin.
