[A Case of Intravesical Foreign Body by Erosion of Surgical Mesh Used for an Inguinal Hernia Repair].

We report our experience with a case in which eroded mesh used for inguinal hernia repair migrated into the bladder. An 84-year-old man underwent surgery for colorectal cancer at the age of 40, and radical surgery for a right inguinal hernia at the age of 83. At his initial visit, he reported macroscopic hematuria.

[A case of testicular tumor presenting with acute scrotum].

A 37-year-old man visited our hospital with a chief complaint of sudden onset of right scrotal pain. Because spermatic cord torsion was suspected, an exploratory incision was made. There was no spermatic cord torsion, but an induration was palpated in a part of the right testis.

The impact of obstructive sleep apnea syndrome on nocturnal urine production in older men with nocturia.

Objective: To investigate the impact of obstructive sleep apnea syndrome (OSAS) on night-time secretion of brain natriuretic peptide (BNP) and antidiuretic hormone (ADH) in older men with nocturia accompanied by nocturnal polyuria.

Materials And Methods: One hundred six men with nocturia aged ≥ 60 years underwent full-night polysomnography to determine whether they had OSAS. Blood count, standard chemistry panel, BNP, urinary ADH, urinary creatinine (u-Cre), and urinary osmolarity were measured at 6:00 AM, and a frequency volume chart was recorded on the same day that polysomnography was performed.

[Chronic urinary retention in women caused by primary bladder neck obstruction : report of two cases treated successfully with transurethral resection of bladder neck].

A 60-year-old female was referred to our hospital for the treatment of chronic urinary retention which had compelled her to continue clean intermittent self catheterization (CIC) for several years. After further examination including physical examinations, urodynamic study, cystography, and urethrocystoscopy, she was diagnosed with primary bladder neck obstruction (PBNO). Transurethral resection of the bladder neck (TURBN) was performed to relieve the bladder outlet obstruction and she was free from CIC thereafter.

[A case of domestic violence-related Page kidney].

Page kidney is caused by the accumulation of blood in the perinephric or subcapsular space, resulting in compression of the involved kidney, renal ischemia and high renin hypertension. We describe a case of domestic violence-related Page kidney. This report also reviews previously described cases of Page kidney.

[Choriocarcinoma presenting as a spontaneous rupture of an adrenal metastasis: a case report].

A 20-year-old woman, who had a history of childbirth, was admitted to the emergency room with an acute abdomen. An abdominal enhanced computed tomography (CT) revealed retroperitoneal hemorrhage, leading to life-threatening, and multiple tumors in the liver. Additionally, chest CT also revealed multiple coin lesions in the lung.

Clinicopathological review of 46 primary retroperitoneal tumors.

Objectives: To clarify the clinical factors including diagnostic imaging findings that may correlate with the histopathological malignancy in primary retroperitoneal tumors.

Methods: The clinical backgrounds and imaging findings of 22 benign and 24 malignant primary retroperitoneal tumors were retrospectively investigated, and the prognosis of patients with malignant retroperitoneal tumors was assessed.

Results: There were significant correlations between the presence of symptoms and malignancy (P < 0.

[Operative position suitable for transvaginal excision of urethral diverticulum or closure of urethrovaginal fistula].

Among the various surgeries in female urology, transvaginal excision of urethral diverticulum needs careful and meticulous procedures in order to avoid some operative complications, such as urethral stricture or urethrovaginal fistula. In the present report, we present a woman with urethral diverticulum who initially underwent transvaginal excision of diverticulum in the dorsal lithotomy position, but she was complicated with urethrovaginal fistula postoperatively. Unfortunately, we failed to repair her fistula when she underwent excision of the fistula in the dorsal lithotomy position.

[A case of retrovesical leiomyoma].

We herein report a rare case of leiomyoma in the retroperitoneal space posterior to the urinary bladder. A 61-year-old man came to our department complaining of lower abdominal discomfort. Abdominal and pelvic computed tomographic scan revealed a retrovesical solid tumor on the cranial side to the left seminal vesicle.
