Review Case Reports
[Recurrent spontaneous bladder rupture cured by conservative therapy: a case report].
The patient was a 44-year-old woman, who had undergone radical hysterectomy and postoperative radiation therapy for cervical cancer at the age of 34 years old. In 1998, she was admitted to our hospital with chief complaints of acute abdominal pain and high fever. We made a diagnosis of spontaneous bladder rupture associated with neurogenic bladder dysfunction and radiation cystitis, based on findings of cystoscopy and cystography. ⋯ In 2000, spontaneous bladder rupture recurred, but conservative therapy was effective again. A review of 12 cases of recurrent spontaneous bladder rupture in Japan, including the present case, suggests that proper management of urination for neurogenic bladder dysfunction may be necessary for prevention of recurrent rupture, when the impaired bladder is left after either successful conservative or surgical treatment of bladder rupture. Urinary diversion and augmentation cystoplasty should be considered for repeated rupture of the bladder.

Review Case Reports
[A case of bladder tumor producing granulocyte-colony stimulation factor and parathyroid hormone-related protein].
A 68-year-old woman presented with urinary pain and frequency. Cystoscopy, intravenous pyelography and magnetic resonance imaging showed a huge bladder mass and hydronephrosis of the left kidney. Transurethral resection of bladder tumor (TUR-Bt) was done. ⋯ The tumor cells were positive for G-CSF and PTH-rP immunohistochemical staining. She died of the disease 46 days after the operation. This is the third case of G-CSF and PTH-rP producing bladder tumor in the literature.

Review Case Reports
[A case of asymptomatic urachal cyst in autopsy--histopathological study of urachal cyst and review of the literature of 99 cases during a 10 year period in Japan].
Disorders of urachal remnants are common. While urachal cysts are usually asymptomatic, infection may mimic a variety of acute abdomen. Here we report a very rare case of urachal cyst that protruded in the urinary bladder cavity and among 99 accumulated cases, only 4 cases have been reported similar to this case characterized by intravesical development from 1990 to 1999. ⋯ Histopathologically, the cyst wall was thin and consisted of fibrous connective tissue with muscular tissue and peripheral nerve, and lined by cuboidal epithelium but no inflammatory cells could be seen. Urachal cysts occur in both sexes are affected with equal frequency, and frequently occur in a younger population. In clinical symptoms the umbilical manifestations are predominant in patients younger than 30 years old, while the bladder manifestations are predominant in those older than 30.

A 72-year-old man with back pain on the left side was admitted. Imaging analysis revealed a retroperitoneal mass and a mass in the left iliocostal muscle and the left quadratus lumborum muscle. ⋯ The primary dedifferentiated liposarcoma appeared to have originated from the retroperitoneal space extending into the iliocostal muscle and the quadratus lumborum muscle. Then the mass was thought to have formed accompanied with osteogenesis.

We report a pilot study on a novel protocol of intermittent androgen deprivation (IAD) treatment of prostate cancer (PC), in which androgen deprivation is restarted when serum prostatic specific antigen (PSA) level reached more than 2 ng/ml and is stopped when PSA level decreased below 0.3 ng/ml. Thirty-two patients (aged 60 to 86 years, median 74 years) with prostate cancer (Stage A in 4 patients, B in 20, C in 1, D in 5, and relapse after radical prostatectomy in 2) were treated with IAD. Median serum PSA prior to the start of endocrine therapy was 15.65 (range 2.67 to 306.3) ng/ml. ⋯ The median duration of first off-phase of IAD was 287 days. There was a significant inverse relation between the duration of the first on-phase and testosterone level measured 4 months after the cessation of first on-phase therapy (R = -0.518). These results suggest that our protocol provides a reasonable length of off-phase duration and that the long term-androgen deprivation phase might delay the recovery of the testicular endocrine function which should be maintained during the off-phase of IAD.
