[Case of multiple encrusted stones on the ureteral stent left for 7 years: the efficacy of extracting the ureteral stent on transurethral lithotripsy].

A 48 years-old man had undergone transurethral lithotripsy (TUL) and Extracorporeal Shockwave Lithotripsy (ESWL) for bilateral ureteral stones and bilateral ureteral stents had been placed in 2001. He was lost to the follow-up for about 7 years after the removal of left ureteral stent. He had complained of right back pain and fever for two months.

[Assessment of quality of life in women with pelvic organ prolapse: conditional translation and trial of P-QOL for use in Japan].

Introduction: A purpose of the surgical treatment for pelvic organ prolapse (POP) is not only the anatomical restoration of the patients but also the improvement of their quality of life (QOL). We have no linguistic validated questionnaire in Japanese to assess it. Therefore we have translated 'prolapse quality of life questionnaire (P-QOL)' into Japanese and present it to the thirty POP patients at our institute for evaluating mental and physical condition before and three months after the operation.

A case of spontaneous pneumothorax during pregnancy and review of the literature.

Spontaneous pneumothorax is rare during pregnancy. A case of spontaneous pneumothorax occurring at 34 weeks' gestation in a healthy 25-year-old primigravida is described. Its occurrence was accompanied by sudden onset of dyspnea and pleuritic chest pain while the patient was walking.

Nerve preservation in tension-free vaginal mesh procedures for pelvic organ prolapse: a cadaveric study using fresh and fixed cadavers.

The aims of this study were, using fixed and fresh cadavers, to clarify how closely the pelvic splanchnic nerve, levator ani nerve (LAN), and sacrospinous ligament (SSL) are located and to examine how to avoid nerve injury during the posterior tension-free vaginal mesh procedure (TVMP), in which mesh is applied through the SSL. Macroscopic dissection of fixed cadavers demonstrated that the LAN crossed the inside of the SSL at a point 0-18 mm medial to the ischial spine and entered the muscle at a point 12-26 mm inferior to the ischial spine and 40-55 mm anterolateral to the coccyx. Dissection after TVMP of fresh cadavers revealed that the point of penetration of mesh through the SSL was close to the LAN.

Clinical comparison of successful and failed microdissection testicular sperm extraction in patients with nonmosaic Klinefelter syndrome.

Objectives: Testicular sperm extraction (TESE), together with intracytoplasmic sperm injection, has become the treatment of choice for patients with nonobstructive azoospermia related to nonmosaic Klinefelter syndrome (KS) who want to father children. However, predicting successful microdissection TESE for patients with KS remains controversial. Thus, we conducted a study to determine whether the prediction of successful microdissection TESE is possible in patients with nonmosaic KS.

[Reaction to blood transfusion recognized by sudden onset of red urine during operation].

A 54-year-old woman was scheduled for the total hip replacement. She was anesthetized with continuous epidural blockade combined with general anesthesia using oxygen, sevoflurane, and propofol. When she received her autologous blood transfusion, we noticed the obstruction of the venous line, and pushed 30 ml of blood with 10 ml syringe.

[Complications of tension-free vaginal tape procedure: a comparison of the vaginal and abdominal approaches].

Objectives: The objectives of this clinical study is to demonstrate our experience of the abdominal approach (from the abdominal wall to the vagina) for the tension-free vaginal tape (TVT) operation and to identify factors responsible for complications relating to the puncture.

Materials And Methods: One hundred and fifty-one cases of patients with stress incontinence who underwent the tension-free vaginal tape operation were analyzed. Among them, 75 cases underwent the TVT procedure with the vaginal approach (from the vagina to the abdominal wall) and the remaining 76 cases underwent the TVT procedure with the abdominal approach (from the abdominal wall to the vagina).

[Acute eosinophilic pneumonia suggesting the involvement of health food].

Purpose: To determine pretreatment parameters which predict improvements following varicocele repaire in semen quality.

Materials And Methods: We retrospectively evaluated a total of 139 infertile patients who underwent varicocelectomy from February 1995 to March 2000. A logistic regression analysis was performed to identify parameters associated with improvements in semen quality.

[Safety and efficacy of a new vessel-sealing device for laparoscopic varicocelectomy].

Purpose: To evaluate the safety and efficacy of a new vessel-sealing device (LigaSure) for laparoscopic varicocelectomy.

Materials And Methods: To evaluate the safty, after elective varicocelectomy, the internal spermatic veins (n = 8) were sealed ex vivo with a 5-mm laparoscopic Maryland-style LigaSure (LigaSure Lap), and bursting pressures were measured. To evaluate the efficacy, a retrospective review of our clinical experience with LigaSure (n = 13) and clip (n = 13) in laparoscopic bilatelal varicocelectomy from June 2000 to October 2002 was performed and certain parameters were abstracted, including operative time, estimated blood loss and perioperative complications.

Impact of age, follicle stimulating hormone and Johnsen's score on successful sperm retrieval by microdissection testicular sperm extraction.

The spermatozoa retrieval rate achieved by microdissection testicular sperm extraction (TESE) for patients with non-obstructive azoospermia is still approximately 50%, despite technical advances. Predicting a successful outcome is important to avoid unnecessary surgery. A study was conducted to determine a method for calculating the predicted probability of successful microdissection TESE.

Hepatic segmentectomy on primary liver cancer with situs inversus totalis.

We present the first case treated by hepatic segmentectomy in a 69-year-old woman with primary liver cancer and situs inversus totalis. The situs inversus did not cause any technical problems during the operation, which was conducted under guidance of intraoperative ultrasonography.

Calcitonin-like polypeptides without apparent biological activity in a patient with recurrent medullary thyroid carcinoma.

A 51-year-old male with a recurrent medullary thyroid carcinoma (MTC) showed high serum levels of calcitonin (CT) and carcinoembryonic antigen (CEA) but with concomitant normocalcemia. The CT activities of the patient's serum in vivo (hypocalcemic activity in rats) and in vitro (cyclic AMP-increasing activity in cultured human mammary tumor, T47D) were much lower than those expected from the patient's CT level. High performance liquid chromatography (HPLC) with radioimmunoassay (RIA) detection gave a broad spectrum of molecular weights of CT-like polypeptides in the 3 kDa to 200 kDa range with separation from CEA, suggesting that the mechanism for CT production in MTC is an obscure one.
