    Beschreibung / Inhaltsverzeichnis: The book provides practicing urologists and diagnostic surgical pathologists (and physicians in training) with immediately useful information in their patients' care. This intends to bridge the gap between pathologists and urologists by providing mutually important updated information. In the format of Question/Answer (Q/A), Professor Oyasu answers a number of questions from practicing and academic urologists, while reviewing the leading pathology and urology journals worldwide and extracted the updated information. This book covers many issues of which the clinician needs to be aware in regard to the pathology of tumors of the adrenal, kidney, urothelium, prostate and testes. This book is designed to be easy to review and to find the key answer. Each question is followed by a succinct answer and comments supported by references with generous use of full color photographs/illustrations. This series of Q/As is useful to a diagnostic surgical pathologist as well, in providing what urologists want to hear from him in his report.

    Notizen: Background We evaluated the safety and efficacy of transurethral electrovaporization of the prostate (TVP) as a new alternative treatment for patients with benign prostatic hyperplasia. Methods A total of 22 patients with symptomatic benign prostatic hyperplasia, including 4 with urinary retention, underwent TVP. If enough of a cavity was not created after 60 minutes of vaporization, transurethral resection of the prostate (TURP) was performed successively. International Prostate Symptom Score (l-PSS) with quality-of-life index, maximum flow rate, and postvoid residual volume were measured at baseline and at 2 weeks, 1, 3, and 6 months. A pressure-flow study was performed at baseline and at 3 or 6 months after surgery. Results TURP was required in 10 of 22 patients. At 6 months, mean l-PSS decreased from 20.0 to 5.2, quality-of-life index decreased from 4.6 to 1.1, mean maximum flow rate increased from 6.9 to 16.7 mL/s, and postvoid residual volume decreased from 152 to 32 mL. Detrusor pressure at maximum flow decreased from 108 to 39 cm H20, with a significant relief of bladder outlet obstruction in 93% of the patients. Mean decrease in hematocrit was 4.4%, and in serum sodium, 4.8 mEq/L. None of the patients required transfusions or had TUR syndrome. A urethral stricture and a severe stress incontinence developed in 1 patient. Conclusion TVP seems to be a safe and effective alternative to a standard TURP associated with fewer intraoperative complications. Although preliminary clinical results have been promising, further study is necessary to establish long-term efficacy and safety of this procedure.

    Notizen: Background: We retrospectively studied the results of diagnostic imaging using 3 different modalities to determine their usefulness for preoperative localization of the parathyroid, and whether accurate preoperative localization information could be used to modify the surgical approach for parathyroidectomy in patients with primary hyperparathyroidism. Methods: Images of 37 parathyroid adenomas or hyperplasias in 35 patients with primary hyperparathyroidism were obtained using ultrasonography, computed tomography, and subtraction scintigraphy (using thallium 201 [thallous chloride] and either iodine 123 or technetium 99m pertechnetate [99mTcO4]). Results: Approximately three fourths of the adenomas or hyperplasias were successfully identified by ultrasound (76.7%) and computed tomography (76.4%), even when the weight of the tumor was less than 500 mg. However, subtraction scintigraphy was of limited use (61.3% successfully identified). A combination of these modalities gave excellent results for detecting adenomas and hyperplasias, leading to an accurate prediction rate of 96.0%. Conclusion: We conclude that using the combination of these 3 imaging modalities is very useful for the detection of parathyroid adenomas and hyperplasias, and that with such accurate localization information, the unilateral approach alone, or even simple excision of the parathyroid tumors might be feasible, enabling less invasive surgical treatment.

    Notizen: We report a case of bilateral (2.4-cm left and 6.5-cm right) adrenal pheochromocytoma in a 27-year-old man that was treated by laparoscopic adrenalectomy. The patient had no evidence of multiple endocrine neoplasia, type II. The left adrenalectomy was performed first, with the patient in a semilateral position, and then the patient was turned before the procedure was begun on the right side. His postoperative convalescence was uneventful, and he continues corticosteroid replacement therapy. Transperitoneal laparoscopic adrenalectomy can be a safe procedure for bilateral pheochromocytoma, if the patients are carefully selected and the procedures are performed by experienced laparoscopists.

    Notizen: Background Continent urinary reservoirs (CUR) have become one of the major options for patients requiring urinary diversion to improve their quality of life (QOL). To assess whether CUR enhanced postoperative QOL, we surveyed patients with CUR and ileal conduit (IC) using a questionnaire sent by mail. Patients and Methods The questionnaire consisted of 133 questions that covered physical and mental status, social life, sexual habits and symptoms related to urinary diversions. A total of 1 72 questionnaires were sent out, and 137 (80%) patients (74 CUR and 63 IC patients) responded. Results Basic physical conditions were similar in the 2 groups, except for sleeping habits. Regarding social life, however, the CUR group showed better scores in bathing habits and frequency of overnight travel. Parasternal dermatitis was more frequent in the IC group and the patients were more hesitant to show their stoma to others. On the other hand, about half of the patients in the CUR group complained of troublesomeness in self-catheterization, especially at night. Overall, 74% and 41% of the patients in the CUR and IC group were satisfied with their urinary diversion. When the Kock pouch and Indiana pouch were compared, no statistically significant differences were found in average capacity, maximum capacity, or frequency of self-catheterization. Conclusions CUR recipients have enhanced QOL regarding the stoma, travel and sleeping habits as compared to ileal conduit. However, troublesomeness of night time self-catheterization was noted in the CUR group. Individualized selection of the type of urinary diversion with informed consent is essential.

    Notizen: Background The prevalence of lower urinary tract symptoms was determined by survey as an initial step in estimating the significance of benign prostatic hyperplasia (BPH) in Asia and Australia. Methods The symptom index (0 to 35) and quality-of-life (QOL) index (0 to 6) of the international prostate symptom score were measured in 7588 men in 9 Asian countries and 146 men in Australia. Results The percentages of Asian men considered to be symptomatic (symptom index ≧ 8) were 18%, 29%, 40%, and 56% in the age groups of 40 to 49, 50 to 59, 60 to 69, and 70 to 79 years, respectively. For Australian men, these figures were 36%, 33%, and 37% in the 50 to 59, 60 to 69, and 70 to 79 year age groups, respectively. Conclusions Our estimates indicate that the prevalences of symptomatic men in Asia and Australia are similar to or greater than those in Europe and America, and suggest BPH is similarly common in these areas.

    Notizen: Abstract Background The changes over time of the annual incidence of lower urinary tract stones in Japan from 1965 to 1995 were analyzed.Methods Data on lower urinary tract calculi were abstracted from the past three nationwide surveys of urolithiasis, which covered nearly all major hospitals and urologists in Japan and enumerated all outpatient visits diagnosed as urolithiasis in the years 1965, 1975, 1985 and 1995. Chronological changes in the sex- and age-related annual incidences of lower urinary tract stones and stone composition were estimated.Results Lower urinary tract stones were predominant in men 60 years of age or older. Between 1965 and 1995, the annual incidence has significantly decreased in men ≥ 60 years of age from 37.2 to 27.0 per 100 000 and significantly increased in women ≥ 60 years of age from 2.4 to 4.8 per 100 000. In men, an increased proportion of uric acid and calcium stones as well as a decreased frequency of infection stones is a phenomenon common to upper urinary tract stones. However, infection and calcium stones have been two major stone types in women.Conclusions In contrast to upper urinary tract calculi, the incidence of lower urinary tract stones has decreased over the last 30 years in men ≥ 60 years of age predisposed to this disease.
