Endometriosis is a common disease found in reproductive age women, but pulmonary endometriosis is rare. We present a 21-year-old female with catamenial chest pain, chest tightness, severe cough, and hemoptysis. Though we could not find any definite intrapulmonary endometriotic lesion by computed tomography and bronchoscope, she was diagnosed to have pulmonary endometriosis due to the typical clinical symptoms. After 6 months of GnRH agonist application, the symptoms were completely relieved. She has been followed up and has been symptoms free for at least 6 months after administration of GnRH agonist.

Leiomyoma are very common in the normal uterus; however, they are rather rare in mullerian duct remnant. We report a case of mullerian duct remnant leiomyoma associated with vaginal agenesis. The mass had papillary growth with cystic-solid components by ultrasound. Ovarian cancer was suspected preoperatively. Finally, a fibroid with hyalinization and chondroid metaplasia was diagnosed histopathologically. To the best of our knowledge, this is the first case of mullerian duct remnant leiomyoma with degeneration, mimicking ovarian cancer by ultrasound. We provide the clinical details of this case and discuss a diagnostic pitfall.

Pancreatic cyst mimicking an ovarian cyst ultrasonographically has not yet been reported. We report an elderly woman with such a huge pancreatic cyst whose initial presentation was low abdominal pain. Ultrasound showed a hypoechoic cyst measuring 13.6 x 13.2 x 11.8 cm occupying pelvic cavity. She received laparotomy under the impression of ovarian cyst. Interestingly, the cyst was found to have originated from the pancreas. Total cyst excision was performed and pathologic report was pancreatic microadenoma. The patient's postoperative course was unremarkable.

Thirty-five patients receiving cystectomy underwent rectosigmoid pouch. The technique of ureteral submucous implantation was described. The follow-up results were analyzed. The relationship of postoperative voiding frequency and preoperative anal closure pressure was assessed. The day and night time continence rate is 97% (34/35). There were no hydronephrosis, no ureterocolonic stricture or reflux. The complications are not unique to rectosigmoid pouch and not high when compared with other forms of urinary diversion. When the preoperative anal closure pressure reaches nearly 100 cmH2O a postoperative outcome with good quality of life will be predicted. With the advantages of high continence rate and simplicity of performance the rectosigmoid pouch will become one of the alternative forms of continent urinary diversion. For obtaining the favorable results a patient with normal renal function, good hepatic function and anal closure pressure more than 50 cmH2O is required.

The transurethral needle ablation (TUNA) of the prostate was performed in 8 patients in chronic urinary retention, all of whom were a poor surgical risk. A special catheter device was used to deliver low-level radiofrequency energy to heat tissue within the prostate to 100 degrees C. After treatment, uroflowmetry, symptom score and quality of life score were evaluated. Tolerance of the procedure with topical anesthesia was satisfactory. Of the 8 patients, 6 (75%) resumed voiding within a mean time of 9.2 days (range 1-21). The mean maximal flow rate was 9.8 +/- 3.2 ml/s (range 5.9-14). Failure to void was associated with a decompensated detrusor function. We conclude that TUNA is effective for patients with urinary retention due to benign prostatic hyperplasia. It seems particularly suitable for treating elderly patients with a high surgical risk.

This in vitro study was undertaken to investigate the effects of adenyl purines in human uterine myometrium and uterine arteries. Segments of uterine myometrium and uterine arteries obtained at hysterectomy were isolated and mounted in tissue chambers. The muscle activity was recorded by polygraph. Adenyl purines agonists, such as adenosine, N-[(R)-1-methyl-2 phenylethyl]-adenosine (R-PIA) and 5-N-ethylcarboxamide adenosine (NECA) produced concentration-dependent contraction in human uterine myometrium. The potency order was NECA = R-PIA > adenosine. Adenosine A1 receptor antagonist: 1, 3-dipropyl-8-cyclopentylxanthine (DPCPX) blocked the effect of adenosine in human uterine myometrium. Otherwise, adenyl purines induced dose-dependent relaxation in human uterine artery precontracted by phenylephrine (PE, 10(-5)M). The potency gradient was NECA > R-PIA > adenosine; the results indicate adenyl purine induces uterine myometrium contraction via A1 receptor. However, adenosine causes uterine artery relaxation by A2 receptor.
