PURPOSE: The main goal of this retrospective study is to explore the predictors of success in learning clean intermittent self-catheterization (CISC) in patients over 65 years of age. The secondary goal is to assess whether in this population, the risk of failure to perform CISC is greater, compared with patients under 65 with similar pathologies. METHODS: All patients older than 65 consulting between January 2011 and January 2016 for learning CISC were included. A control population younger than 65 matching with sex, body mass index, and pathology was selected. RESULTS: One hundred sixty-nine of the 202 patients (83.7%) over 65 succeeded in learning CISC. Obesity (P < 0.05), low pencil and paper test (PP test) (P < 0.01) and low functional independence measure (FIM) (P < 0.01) scores were risk factors of failure. No significant differences were found with sex or pathology. In multivariate analysis, low PP test perineum access (odds ratio [95% confidence interval], 2.30 [1.32–4.42]), low FIM motor (1.04 [1.01–1.08]), and FIM cognition (1.18 [1.03–1.37]) scores were independent factors of learning failure. Compared to control group, age over 65 was not predictive of failure (P=0.15). CONCLUSIONS: Our study shows that success in learning CISC does not depend on age but on difficulties in mobility, access to perineum and probably cognitive disorders.

Vesicoenteric fistula is a rare complication of bladder squamous cell carcinoma. We report the case of a 70-year-old male who complained of painless, total gross hematuria. Abdominopelvic computed tomography (CT) revealed an approximately 2.7-cm lobulated and contoured enhancing mass in the bladder dome. We performed partial cystectomy of the bladder dome after transurethral resection of the bladder. The biopsy result was bladder squamous cell carcinoma, with infiltrating serosa histopathologically, but the resection margin was free. Postoperatively, follow-up CT was done after 3 months. Follow-up CT revealed an approximately 4.7-cmx4.0-cm lobulated, contoured, and heterogeneous mass in the bladder dome. A vesicoenteric fistula was visible by cystography. Here we report this case of a vesicoenteric fistula due to bladder squamous cell carcinoma.

The aim of this study was to figure out the predictors of early postoperative catheter-related bladder discomfort (CRBD) after urological surgery. We designed a prospective observational study in our hospital. Consecutive adult patients undergoing surgery under general anaesthesia or epidural anaesthesia necessitating urinary catheterization were included during a 3-month period. severity of bladder discomfort was assessed on a 4-point scale: (1) no pain, (2) mild pain (revealed only by interviewing the patient), (3) moderate (a spontaneous complaint by the patient of a burning sensation in the urethra and/or an urge to urinate and/or sensation of urethral foreign body without any emotional agitation) and (4) severe discomfort (agitation, loud complaints and attempt to remove the bladder catheter associated with a burning sensation in the urethra). Predictors of CRBD were identified by univariate and multivariate analysis. Totally, 116 patients were included, of which 84.5% had CRBD (mild CRBD: 40.5%; moderate or severe CRBD: 44.0%) at day 1, while 31.9% developed CRBD (mild CRBD: 29.3%; moderate or severe CRBD: 2.6%) at day 3. We evaluated 9 potential forecast factors of CRBD, and univariate Chi-square test showed male gender [OR=2.4, 95%CI (1.1-5.6), P<0.05], abdominal open surgery compared with transurethral surgery [OR=0.3, 95%CI (0.1-0.6), P<0.05], abdominal surgery compared with laparoscopic surgery [OR=3.3, 95%CI (1.2-8.9), P<0.05] and history of catheterization [OR=0.5, 95%CI (0.2-0.9), P<0.05] were independent predictors of moderate or severe CRBD in the patients after surgery. While multivariate logistic regression analysis showed that the abdominal open surgery [EXP(B)=3.074, 95%CI (1.3-7.4), P<0.05] and the history of catheterization [EXP(B)=2.458, 95%CI (1.1-5.9), P<0.05] might contribute more to the occurrence of moderate or severe CRBD. In conclusion, this observational study identified that the type of surgery and the history of catheterization might be predictive factors of moderate and severe CRBD after urological surgery.

Multiple system atrophy (MSA) is a rare, yet fatal neurodegenerative disease that presents clinically with autonomic failure in combination with parkinsonism or cerebellar ataxia. MSA impacts on the autonomic nervous system affecting blood pressure, heart rate and bladder function, and the motor system affecting balance and muscle movement. The cause of MSA is unknown, no definitive risk factors have been identified, and there is no cure or effective treatment. The definitive pathology of MSA is the presence of alpha-synuclein aggregates in the brain and therefore MSA is classified as an alpha-synucleinopathy, together with Parkinson's disease and dementia with Lewy bodies. Although the molecular mechanisms of misfolding, fibrillation and aggregation of alpha-synuclein partly overlap with other alpha-synucleinopathies, the pathological pathway of MSA is unique in that the principal site for alpha-synuclein deposition is in the oligodendrocytes rather than the neurons. The sequence of pathological events of MSA is now recognized as abnormal protein redistributions in oligodendrocytes first, followed by myelin dysfunction and then neurodegeneration. Oligodendrocytes are responsible for the production and maintenance of myelin, the specialized lipid membrane that encases the axons of all neurons in the brain. Myelin is composed of lipids and two prominent proteins, myelin basic protein and proteolipid protein. In vitro studies suggest that aberration in protein distribution and lipid transport may lead to myelin dysfunction in MSA. The purpose of this perspective is to bring together available evidence to explore the potential role of alpha-synuclein, myelin protein dysfunction, lipid dyshomeostasis and ABCA8 in MSA pathogenesis.

OBJECTIVETo analyze the change in the incidence of pheochromocytomas in adrenal medulla or extra-adrenal and multiple endocrine neoplasm type 2 (MEN2), to summarize the clinical characteristics of benign, potentially malignant and malignant pheochromocytomas and to investigate the correlation between clinical manifestations and pathological changes.

METHODSStatistic analysis was performed to detect the incidence, constituent ratio, mean diagnostic age, sex proportion and correlation between clinical manifestions and pathologic changes in pheochromocytomas in adrenal medulla or extra-adrenal gland and MEN2 from 1993 to 2008 in the Department of Pathology, the General Hospital of Tianjin Medical University with Runs test, ANOVA, t test and chi-square test.

RESULTSThe total number of biopsies within the 16 years was 167 702 cases (average 10 481 cases per year). The numbers (detectable rate) of total adrenal diseases, pheochromocytomas in adrenal medulla and extra-adrenal glands were 910 (0.54%), 139 (0.08%), and 42 (0.03%) cases, respectively. The numbers (constituent ratio) of benign, potentially malignant and malignant of pheochromocytomas in adrenal medulla were 102 cases (73.4%), 29 cases (20.9%) and 8 cases (5.7%), respectively; in the 102 cases of benign tumors, patients with MEN2 were 8 (7.8%); the three groups of the tumors in extra-adrenal sites were 18 (42.8%) cases, 12 (28.6%) cases and 12 (28.6%) cases. There were no changes in the detectable rate and constituent ratio of adrenal diseases, benign, potential malignant and malignant pheochromocytomas in adrenal medulla or extra-adrenal glands and patients with MEN2 during the past 16 years (P > 0.05), but there was a tendency that malignant transformation was gradually increased with age, which was more commonly found in male patients than females. The mean age at diagnosis of patients with benign and potentially malignant pheochromocytomas was 42.7 years (ranged from 10 - 74 years), and 40.1 years (13 - 66 years), respectively, which were younger than patients with malignant pheochromocytomas (51.6 years, P < 0.05); the mean age of patients with benign and potentially malignant pheochromocytomas in extra-adrenal sites was 43.1 years (ranged from 20 - 75 years) and 45.2 years (28 - 65 years) that were older than those with malignant (37.8 years, ranged from 14 - 58 years, P < 0.05). It was spectacular that patients with malignant pheochromocytoma in adrenal medulla (51.6 years) were older than that in extra-adrenal sites (37.8 years); all the patients with MEN2 were female benign pheochromocytoma in adrenal medulla, whose age (38.9 years) was younger than that of benign lesions (42.7 years, P < 0.05), in which thyroid medullary carcinoma appeared early than pheochromocytomas in adrenal medulla. The detectable rate of hypertension in patients with malignant pheochromocytomas in adrenal medulla and in extra-adrenal sites were less than that in benign and potentially malignant ones (P < 0.05). The bilateral lesions more commonly found in malignant pheochromocytoma (25.0%) than benign (15.7%) and potentially malignant pheochromocytomas (6.9%) only in adrenal medulla. Relapse rates in both adrenal and extra-adrenal tumors were rising from benign (11.8%, 0), potentially malignant (13.8%, 25.0%), to malignant (33.3%, 37.5%) groups; the average diameter of pheochromocytomas in both adrenal and extra-adrenal sites was increasing from benign (4.2 cm, 4.0 cm), potentially malignant (5.3 cm, 5.6 cm) to malignant (7.3 cm, 6.9 cm) groups (P < 0.05).

CONCLUSIONSThe diagnostic criteria of benign, potentially malignant and malignant pheochromocytomas in adrenal medulla and in extra-adrenal sites are well established according to the WHO classification of endocrine tumors (2004). The closer relationship is found between clinical manifestations and pathologic changes. The definite type and nature of pheochromocytomas are mainly rested upon the pathologic examination.

A 59-year-old Korean man complained of a painless scrotal hard nodule and weak urine stream. The ultrasound scan revealed a 2.2-cm sized round heteroechogenic nodule located in the extratesticular area. Microscopic hematuria was detected in routine laboratory examinations. On scrotal exploration, multiple spargana were incidentally found in the mass and along the left spermatic cord. On cystoscopy, a 10-mm sized mucosal elevation was found in the right side of the bladder dome. After transurethral resection of the covered mucosa, larval tapeworms were removed from inside of the nodule by forceps. Plerocercoids of Spirometra erinacei was confirmed morphologically and also by PCR-sequencing analysis from the extracted tissue of the urinary bladder. So far as the literature is concerned, this is the first worm (PCR)-proven case of sparganosis in the urinary bladder.

Dystrophic calcification can be defined as a calcification that occurs in degenerated or necrotic tissue. It is associated with multiple clinical conditions, such as collagen vascular diseases. It involves the deposition of calcium in soft tissues despite no generalized disturbance in the calcium or phosphorus metabolism, and this is often seen at sites of previous inflammation or damage. Potassium-titanyl phosphate (KTP) laser vaporization of the prostate is safe and relatively bloodless procedure that results in a shorter catheterization, immediate symptomatic improvement, and less severe postoperative irritative symptoms. However, longer follow-up studies or reports about complications are lacking. Here in we report a case of dystrophic calcification and stone formation on the entire bladder neck after performing KTP laser vaporization of benign prostate hyperplasia. That was treated by lithotripsy and transurethral resection.

A 70-year-old man with past history of hemicolectomy due to colon cancer underwent a follow-up abdominal/pelvic CT scan. CT revealed a right adrenal metastasis and then he underwent FDG-PET/CT study to search for other possible tumor recurrence. In PET images, other than right adrenal gland, there was an unexpected intense FDG uptake at right inguinal region and at first, it was considered to be an inguinal metastasis. However, correlation of PET images to concurrent CT data revealed it to be a bladder herniation. This case provides an example that analysis of PET images without corresponding CT images can lead to an insufficient interpretation or false positive diagnosis. Hence, radiologists should be aware of the importance of a combined analysis of PET and CT data in the interpretation of integrated PET/CT and rare but intriguing conditions, such as bladder herniation, during the evaluation of PET scans in colon cancer patients.

OBJECTIVE: We have performed Classic Intrafascial Supracervical Hysterectomy (CISH) since April 1993, so we are to report the clinical results of CISH for 10 years, and introduce the technical aspects of new CISH. METHODS: A retrospective analysis on 470 cases of CISH (conventioal and new method) was carried out including age, parity, operating time, blood loss, uterine weight, pathologic results, complications and postoperative recovery. RESULTS: The mean age was 44.8 years (range 25-68), parity 2.23 (0-9), operating time 131 minutes (70-310), mean blood loss 148 mL (20-1000) and mean uterine weight was 306 gram (90-880). The most common uterine pathology was uterine leiomyoma (49.3%) and there were adenomyosis (15.5%), leiomyoma with adenomyosis (12.5%), chronic cervicitis (5%) and so on. Intraoperative complications included one case of bladder injury due to thick adhesion and 6 cases of bleeding requiring transfusion. Postoperative complications included 5 cases of cervical coring site bleeding, 2 cases of febrile complications, 2 cases of trocar site bleeding, 1 case of transient nerve injury of lower extremity, and 1 case of urinary tract infection. The mean hospital stay was 5.3 days (3-10). two hundreds and seventy eight patients of 470 had been followed for cervical pathology, and no pathologic findings except 3 cases of mild dysplasia were shown. CONCLUSION: Classic intrafascial supracervical hysterectomy, a minimally invasive organ-preserving procedure indicated for benign uterine disease, is associated with few operative complications and low morbidity, and the disadvantages of conventional Semm's CISH technique can be overcome by new CISH technique using triple ligation method.
