Pelvic fistulas may result from obstetric complications, inflammatory bowel disease, pelvic malignancy, pelvic radiation therapy, pelvic surgery, or other traumatic causes, and their symptoms may be distressing. In our experience, various types of pelvic fistulas are identified after pelvic disease or pelvic surgery. Because of its close proximity, the majority of such fistulas occur in the pelvic cavity and include the vesicovaginal, vesicouterine, vesicoenteric, ureterovaginal, ureteroenteric and enterovaginal type. The purpose of this article is to illustrate the spectrum of imaging features of pelvic fistulas.

PURPOSE: To evaluate the effects and usefulness of fiuroscopy guided celiac ganglion block after marking of needle path with CT scan. MATERIALS AND METHODS: Celiac ganglion block with 100% ethyl alcohol was performed in 50 cancer patients who were inoperable and had intractable abdominal pain. Duration and degree of pain relief after the procedure and its complication were analyzed. RESULTS: Early pain relief was observed in 98% and long term relief in 68% without serious complication. CONCLUSION: Fluoroscopy guided celiac ganglion block after marking of needle path with CT scan was a safe and valuable procedure in relieving intractable pain in terminal cancer patients and reduced the time in the CT room.

PURPOSE: The purpose of this study was to evaluate the CT findings of renal parenchyma infiltrated by pelvocalyceal transitional cell carcinoma. MATERIALS AND METHODS: This study included 28 patients in whom transitional cell carcinoma was dignosed after nephrectomy. CT findings were analyzed for the presence or absence of renal parenchymal infiltration; diagnostic criteria for this included parenchymal inhomogeneous low attenuation, ill-defined margin between the mass and renal parenchyma, or focal calyceal dilatation. To detect renal parenchymal infiltration by transitional cell carcinoma, we evaluated the frequency, sensitivity and specificity of each CT finding. RESULTS: Pathologic reports showed that renal parenchymal infiltration had occurred in 17 of 28 patients, (60.7%) ; on CT scans, renal parenchymal infiltration was seen in 15 of these 28 (53.6%). It two patients who did not show CT findings of renal parenchymal infiltration, pathologic examination revealed parenchymal invasion. All 15 patients who showed renal infiltration on CT had parenchymal inhomogeneous low attenuation (sensitivity: 88.2%, specificity : 100%), 13 showed ill-defined margin of the mass (sensitivity : 76.5%, specificity : 100%), and six showed focal dilatation of the calyx (sensitivity : 35.3%, specificity : 100%). CONCLUSION: In patients with pelvocalyceal transitional cell carcinoma, CT findings of parenchymal inhomogeneous low attenuation, ill-defined margin of mass, and focal calyceal dilatation suggest renal parenchymal infiltration, and these findings may be helpful in preoperative prognosis.

This study was carried out to evaluate and investigate the clinical utility of the plastic nasolacrimal stents (Song's tube) without fluoroscopic guidance in treatment of the obstructed nasolacrimal duct. The anesthesia was performed with Tetra-caine contained epinephrine in the nasal mucosa, proparcaine in the conjunctival sac and 2% lidocaine for infratrochlear block. The plastic stent were placed in the lacrimal system with the head portion lying in the lacrimal sac and body in the nasolacrimal duct and projecting into the inferior meatus of the nasal cavity. Complete resolution of epiphora was accomplished in 92(97%) of the 95 eyes with mean follow up of 8.5 months (minimal 6 months, maximal 18 months), and there were no significant complications under this procedure. This noninvasive procedure was indicated the anatomic obstruction of the nasolacrimal system, especially obstruction was at the junction between the lacrimal sac and nasolacrimal duct or stenosis of the nasolacrimal duct, which can be the probing as possbile. The use of the plastic nasolacrimal stents without fluoroscopic guidance have many advantages, as follow; There are no surgical dacryocystorhinostomy procedure, simple surgical technique and short duration of procedure, no risk of exposure radiation, and no needs of fluoroscope instrument and radiologist. Although evaluation of a longer-term follow up will be needed to determine the effectiveness of this thechnique, the utility of the plastic nasolacrimal stents without fluoroscopic guidance seem to be of value in primary management of the obstructed nasolacrimal duct, prior to the dacryocystorhinostomy procedure in proper indication of the nasolacrimal duct obstruction.

Ectopic ureter entering into the seminal vesicle associated with ipsilateral renal dysplasia is a very rare developmental abnormality. Clinical manifestations consists of dysuria, hematuria, recurrent epididymitis. ejaculatory pain and perineal discomfort and the diagnosis is made by seminal vesiculogram through vas deference. Surgical excision of the seminal vesicle and the ectopic ureter is the best choice or treatment in this entity. We present a case of 34 year old infertile man with ectopic ureter entering into the seminal vesicle associated with ipsilateral renal dysplasia and contralateral cryptorchidism.

Tumors or tumor-like lesions in the prostate raise questions concerning their histogenesis and they may have prognoses dissimilar to those of prostatic adenocarcinoma. Several neoplasms involving the prostate have been described and characterized in recent years. In addition to adenocarcinoma, they include mucinous cystadenocarcinoma, neuroendocrine cancer, lymphoma, spindle cell neoplasm, squamous cell carcinoma, transitional cell carcinoma, and benign prostatic hyperplasia (BPH) mimicking malignancy. In addition, infectious conditions such as tuberculosis and some stages of prostatic abscess can also mimic prostate tumors. Radiologic findings overlap and have limited roles in the diagnoses of these entities. However, knowledge of these variable tumors and tumor-like conditions is helpful when making accurate radiologic diagnoses, which have important clinical implications for treatment and prognosis. Transrectal ultrasound (TRUS) and available pathologic images of unusual tumors and tumor-like lesions are demonstrated in this article.

This study examined the influence of age, sex, blood pressure, and obesity index on intraocular pressure (IOP), in order to investigate the relationship between the upper limits of the following two conditions in the general Korean population: the "systolic or diastolic hypertensive and obese" group and the "systolic or diastolic hypotensive and lean" group. A total of 6828 healthy subjects (13,656 eyes) underwent automated multi-phasic tests, including tonometry, blood pressure, visual field, and body mass index. The 6,828 subjects were divided into five groups based on age; less than 40, 40 to 49, 50 to 59, 60 to 69, and over 70 years old. They were also divided into four categories on the basis of sex, age, blood pressure, and obesity index. The mean IOP in males (15.8+/-3.3 mmHg) was significantly higher than in females (14.8+/-3.1 mmHg) (P < 0.05), but this difference decreased proportionally with increasing age. IOP had a tendency to decrease with increasing age (P < 0.05). IOP increased significantly with increasing systolic blood pressure, diastolic blood pressure and obesity index (all, P < 0.05). The mean IOP of the "systolic or diastolic hypertensive and obese" group was higher than that of the "systolic or diastolic hypotensive and lean" group in the general Korean population (P < 0.05). These data could aid investigation into the epidemiological, etiologic and oriental influences related to the risk factors of glaucoma, especially in oriental populations.
