ROLES OF BPH IMPACT INDEX IN THE EVALUATION OF IMPAIRED URINATION IN PATIENTS WITH BPH

The Japanese Journal of Urology (2005)

Isao Ikemoto Hiroshi Kiyota Yasuyuki Suzuki Yukihiko Oishi Kouichi Kishimoto

(Objective) To assess the significance and current status of the benign prostatic hyperplasia (BPH) impact index (BII) in the evaluation of subjective symptoms of impaired urination in so-called QOL disease, BPH.(Patients and Methods) Over the past 2 year-period, in 159 patients with the diagnosis of BPH were asked to reply to each of the international prostate symptom score (I-PSS), QOL index and BII questionnaires. The subjective symptom scores (a total of 246 points) were evaluated from the viewpoint of clinical statistics in the search for any these and to find which questions cover the BII, most.(Results) 1) Statistically significant but moderate correlations were observed among I-PSS total score, QOL index and BII. The correlations among Qmax, BII and QOL were very weak. 2) Out of the 11 domains in both IPSS and BII, 2 questions of BII ("bothersomeness caused by urinary problems" and "degree of worry about well-being") and 4 questions of IPSS ("residual sense, " "pollakisuria, " "weak urinary stream" and "nocturia") were shared as QOL indices. Patient satisfaction was affected also by the questions in the BII. 3) Of the 7 BPH symptoms assessed in IPSS, 4 symptoms ("residual sense, " "pollakisuria, " "weak urinary stream" and "nocturia") affected the QOL index, and 4 symptoms ("urgency on micturition, " "residual sense, " "nocturia" and "strain at urination") affected BII. 4) Of the 7 symptoms assessed by IPSS, different symptoms affected each of the 4 BIT questions.(Conclusion) It is needed to assess BPH symptoms not only by the IPSS and QOL index but also based on BII to provide the detailed therapeutic instructions and thorough patients consultation.

[Sclerosing Sertoli cell tumor of the testis: a case report].

We report here a case of sclerosing Sertoli cell tumor of the testis. A 21-year-old male, who complained of right testicular pain, visited a Jikei University affiliated hospital on May 30th, 1999. A small nodule with a diameter of 6 to 7 mm was palpable on the central surface of the right testis. No tumor markers for testicular cancer, such as hCG-beta and alfa-fetoprotein, were elevated. However, ultrasound revealed a hypoechoic mass with increased blood flow. Therefore, we performed right high orchiectomy under the diagnosis of right testicular cancer. Pathological diagnosis of this tumor was sclerosing Sertoli cell tumor. Neither recurrence nor metastasis has been found for 12 months postoperatively.

[Schwannoma with purely cystic form originating from the adrenal area: a case report].

A 62-year-old woman was hospitalized with complaints of right upper abdominal discomfort. Various imaging studies showed an extremely large suprarenal mass with solitary cystic formation. Partial adrenalectomy was successfully performed through the transperitoneal approach. The resected mass measured 12 x 10 x 10 cm and weighed 600 g. A pathological examination showed an Antoni-B predominant-type benign schwannoma containing a large volume of degenerative fluid. Our search of literature yielded few reports of solitary cystic schwannomas in the retroperitoneal cavity or throughout the body. This unusual cystic manifestation is thought to be a terminal stage of degeneration of a long-standing schwannoma.

Computed tomography (CT) による腎静脈および下大静脈腫瘍栓塞の診断を4例に行なつたので, その成績について報告した. 症例は1979年1月から6月までの半年間に慈恵大学病院で診療した4例で, 腎細胞癌3例, 腎盂扁平上皮癌1例であつた. 患側は右側3例, 左側1例で, 右側の3例はいずれも腎静脈から下大静脈におよぶ腫瘍栓塞がみられ, 左側の1例は腎静脈内の腫瘍栓塞であつた. 4例とも腎摘出術を行ない, 手術的にも腎静脈および下大静脈の腫瘍栓塞を確め得た例である.4例はすべて, CTにより腎静脈の著明な拡張がみられ, 腎静脈の腫瘍栓塞が診断された。また腫瘍栓塞が下大静脈までおよんでいた3例中2例では, 拡張した腎静脈に連続して軽度に拡張した下大静脈がみとめられ, さらに contrast enhancement 後のCTでは, 1例に下大静脈の充満欠損がみられた. すなわち静脈内の腫瘍栓塞のCTによる所見としては, 腎静脈および下大静脈の拡張がみとめられ, さらに contrast enhancement 後のCTでは静脈内の充満欠損がみられ, 診断上有用であつた.今後CTは腎動脈造影, 下大静脈造影, 超音波検査などとともに用いられる価値があるが, とくに腎動脈造影で striated vascular pattern が描出されない例や, 下大静脈造影での充満欠損が, 腫瘍栓塞によるものか, あるいは腫瘍による圧排によるものか不明確な例に有用であろう.

[A case of complete self-mutilation of penis].

Masayuki Tomita Shigetaka Maeda Takahiro Kimura Isao Ikemoto Yukihiko Oishi

Self-mutilation of the penis is extremely rare. A 69-year-old man was admitted after having amputated his own penis completely from its root. He had no history of psychiatric illness, but his physical condition on admission was abnormal. We performed urethrocutaneostomy, rather than replantation of the penis, because of the danger that he would reinjure himself. The patient was treated by a psychiatrist under a diagnosis of alcoholic dementia. To our knowledge, this is the 24th case of self-mutilation of the penis reported in the Japanese literature.

CLINICAL STUDIES ON INVERTED PAPILLOMA OF THE URINARY TRACT

The Japanese Journal of Urology (1999)

Koji Asano Kazuhiro Abe Nobuki Kato Kenta Miki Nozomu Furuta

(Background) Inverted papilloma of the urinary tract is believed to be a benign neoplasm based on its histologic morphology and clinical behavior. In recent years, however, several investigators have warned against too optimistic an approach, emphasizing the possibility of malignant cellular transformation within the lesion, or its eventual association with other urothelial tumors such as transitional cell carcinoma or carcinoma in situ. We here report on 35 clinicopathologically diagnosed cases of inverted papilloma, and present the clinical significance attributed to these lesions in view of the current literature.(Patients and Methods) From 1976 to 1997, 35 cases of inverted papilloma of the urinary tract were treated at our hospital. This report presents the clinical features of these cases, the results of prognosis research, an investigation of the cases in which inverted papilloma and transitional cell carcinoma were found to co-exist, and a discussion of the recurrent cases of inverted papilloma found in previous literature.(Results) The patients ranged from 24 to 77 years of age, with a mean of 54 years, and included 4 women and 31 men. The most frequently occurring symptom was grosshematuria, and more than 90% of the 35 cases occurred in the bladder. In 2 of the 35 cases, transitional cell carcinoma coexisted with the inverted papilloma, at a different location in the bladder in one case and within the same neoplasm in the ureter in the other case. Clinical courses after treatment were followed in 29 of the 35 cases, with a follow-up period of from 8 months to 19 years (mean follow-up, 5 years and 4 months). Of these 29 cases, 2 showed recurrence, one at 16 and one at 30 months after the initial resection. Many previous reports show that the association of inverted papilloma and transitional cell carcinoma is stronger in the upper urinary tract and recurrence of inverted papilloma almost always happens with 2 years.(Conclusion) This study suggests that some cases of urinary inverted papilloma show recurrence or malignant potential. Our results indicate that all cases of urinary inverted papilloma should be treated and followed as cases of low-grade transitional cell carcinomas. Consequently, all cases must be followed for two years or more after the initial operation.

[Countermeasures for urinary incontinence in patients with senile dementia: correlation between urinary incontinence severity, senile dementia severity, and activity of daily living].

PubMed (1992)

Y Suzuki Tatsuya Machida Yukihiko Oishi K Miyazaki Takahiro Okabe

The actual conditions of urinary incontinence in 101 patients with senile dementia (23 men and 78 women, average age 80 years) and their urinary control was studied. The three categories of 1) dementia severity, 2) activity of daily living and 3) degree of urinary incontinence, were each divided into five grades and the patients were evaluated accordingly. The correlation among the grades was studied. Of the 101 patients, 87 had urinary incontinence. These 87 were further subdivided into two groups: an ambulatory patient group (25) in which the patients could manage their own daily activity, and the bedridden group (62). The countermeasures for the first group of patients were, usage of a portable chamber pot for 6 patients and induced urination in 5. An anticholinergic agent was administered to 47 of the bedridden patients. The condition of urinary incontinence was reevaluated in both groups 4 weeks later. A high degree of correlation was observed among the grades of dementia severity, activity of daily living and urinary incontinence severity. After the countermeasures taken, improvement in urinary incontinence was observed in the 6 patients who used a portable chamber pot, and in the 5 patients who were subjected to induced urination. No improvement was seen in urinary incontinence in the bedridden patients who were treated with an anticholinergic agent. In conclusion, countermeasures for urinary incontinence in senile dementia should be indicated primarily for patients who can manage their own daily activity.
