BackgroundThe allocation of outcome of suicide attempters is extremely important in emergency situations. Following categorization of suicidal attempters who visited the emergency room by outcome, we aimed to identify the characteristics and potential needs of each group.MethodsThe outcomes of 1348 individuals who attempted suicide and visited the critical care center or the psychiatry emergency department of the hospital were categorized into 3 groups, "hospitalization in the critical care center (HICCC)", "hospitalization in the psychiatry ward (HIPW)", or "non-hospitalization (NH)", and the physical, mental, and social characteristics of these groups were compared. In addition, multiple logistic analysis was used to extract factors related to outcome.ResultsThe male-to-female ratio was 1:2. The hospitalized groups, particularly the HICCC group, were found to have biopsychosocially serious findings with regard to disturbance of consciousness (JCS), general health performance (GAS), psychiatric symptoms (BPRS), and life events (LCU), while most subjects in the NH group were women who tended to repeat suicide-related behaviors induced by relatively light stress. The HIPW group had the highest number of cases, and their symptoms were psychologically serious but physically mild. On multiple logistic analysis, outcome was found to be closely correlated with physical severity, risk factor of suicide, assessment of emergent medical intervention, and overall care.ConclusionThere are different potential needs for each group. The HICCC group needs psychiatrists on a full-time basis and also social workers and clinical psychotherapists to immediately initiate comprehensive care by a medical team composed of multiple professionals. The HIPW group needs psychological education to prevent repetition of suicide attempts, and high-quality physical treatment and management skill of the staff in the psychiatric ward. The NH group subjects need a support system to convince them of the risks of attempting suicide and to take a problem-solving approach to specific issues.

This report deals with the histologic and gross anatomy of the upper urinary tract (calyces, pelvis, and ureter) as well as the nerve supply to this region. It also covers the physiological transport of urine from the kidneys to the bladder, which is reviewed on the basis of experimental and clinical studies. A pacemaker system present in the proximal calyces has been found to have an important physiological role in urine transport. However, clinical experience has shown that urine transport is not affected by surgery such as pyeloplasty and pyelolithotomy which impairs the activity of this pacemaker. Electron microscopic and histochemical studies as well as the maintenance of urine transport after renal grafting suggest that the nerve supply to the upper urinary tract is not dominant in regard to this function. This study also investigated urinary transportation in the presence of urinary tract obstruction due to various diseases, and demonstrated that urine is also conveyed by gravity and not solely by ureteric peristalsis. The use of internal stenting and percutaneous urinary diversion thus appears to be reasonable. Although the detailed etiology congenital hydronephrosis is still unknown, there is no doubt that it involves dysfunction of the ureteropelvic junction, since urine transport is improved by the endoscopic or surgical formation of a physiological tunnel at this junction which can regulate the volume of urine transported according to urine output. It is important for studies of upper urinary tract function to be conducted in close relation to clinical practice and not to simply be confined to esoteric experimental situations.

A 70-year-old man had a history of total laryngectomy for laryngeal cancer and bilateral inguinal hernia repair 5 years previously. The patient had suffered from difficulty with urination since then and had been treated for prostatic hypertrophy at our department. He developed microscopic hematuria from June 1991, and was admitted because a bladder tumor was detected by cystoscopy. Cystography showed a scrotal bladder hernia with filling defects in the bladder per se and the bladder hernia as well. Cystoscopy revealed tumors in the hernia and in the vicinity of the ureteral orifice. Biopsy indicated transitional cell carcinoma. Voiding cystourethrography showed normal urination and no residual urine. Excision of the tumor-containing hernia, partial cystectomy with right ureteral orifice, and reconstruction of the right inguinal canal were performed on October 25, 1991. The postoperative course was favorable and he was discharged on the 40th postoperative day. The tumors were respectively stage as TCC, G1, and pT1a, and TCC, G1 greater than G2, and pT1b. Thirty five cases of bladder hernia that have been reported in Japan. Eight cases of accompanied by cancer have been reported in Japanese (3 cases) and foreign (5 cases) literatures. These are reviewed and discussed.
