PURPOSE: Caliceal diverticular calculi are mostly asymptomatic. In certain cases they may be associated with chronic or recurrent pain, recurrent urinary tract infections, progressive renal damage and hematur ia. The treatment of symptomatic caliceal diverticular calculi has evolved from open surgery to less invasive procedures, such as extracorporeal shock wave lithotripsy (SWL), percutaneous techniques, retrograde ureteroscopy and laparoscopy, but it remains controversial. Percutaneous techniques are frequently used to address the diverticular stone burden, to fulgurate the diverticular wall, to dilated the diverticular neck and improve drainage. For this reason, we reviewed 33 patients with caliceal diverticular calculi to determine whether they could be treated successfully by percutaneous nephrolithotomy (PCNL) as the initial treatment. MATERIALS AND METHODS: A total of 33 patients with caliceal diverticular calculi underwent PCNL between February 1990 and February 2000. The majority of diverticula were located at the upper pole. Access was gained via a direct target puncture. After sequential dilatation of the tract, stones were removed and the diverticular wall was fulgurated. The diverticular neck was dilated with the Amplatz dilator upto 24-30 Fr. and a 20 Fr. nephrostomy catheter was placed. RESULTS: PCNL was performed successfully in 30 patients (90.9%), but puncture was failed in 3. Mean operative time was 105 minutes and mean hospital stay was 4.5 days. All patients who were treated successfully with PCNL became stone-free without any complication. Mean follow-up was 20 months (ranged from 1 to 108 months). Of the 26 patients with symptoms preoperatively, 25 patients were rendered symptom-free (96.2%). Twenty-four patients were assessed with an intravenous urogram at 1 or 3 months and 6, 12 months and there was no stone recurrence. The diverticula were obliterated or had improved drainage in 95.8% (23/24) of assessable cases. CONCLUSIONS: We confirmed that PCNL is a safe, less invasive and effective procedure and should be considered an acceptable form of primary management of patients with caliceal diverticular stone.

Purpose: To analyze the causes and to prevent dislocations of the hip joint that occur in patients who underwent revisions of total hip arthroplasties by changing only the polyethylene liners and femoral heads, subsequent to primary total hip arthroplasties. Materials and Methods: We evaluated 28 patients who underwent acetabular component revisions of total hip arthroplasties subsequent to primary total hip arthroplasties. The average age of the patients was 55 years old and all 28 patients had operations through the posterolateral approach. In 17 of the cases, the acetabular cups, polyethylene liners, and femoral heads were changed; in 10 cases, just the polyethylene liners and femoral heads were changed; and in 1 case, only the polyethylene liner was changed. Results: We observed 7 cases of hip dislocations that occurred among a total of 28 cases after revisions of total hip arthroplasties. In all 7 cases, the polyethylene liners and femoral heads were changed, but not the acetabular cups. In additional, in all 7 cases of dislocation, the patients were non-compliant and started weight-bearing prematurely after revisions of the total hip arthroplasties Conclusion: We observed new dislocations in the 7 cases in which the polyethylene liners and femoral heads were changed. The main reasons were inadequate soft tissue tension and hip joint laxity. Therefore, it is necessary to increase the neck length, use elevated rim polyethylene liners, readjust the acetabular cups to their optimal positions, and apply hip abduction braces to patients early after revision of total hip arthroplasties in order to lessen the danger of dislocations.

Cerebral arterial embolism which resulted in total occlusion of right proximal middle cerebral artery was occured in 33 years old female patients with severe mitral stenosis and atrial fibrillation during percutaneous mitral balloon valvuloplasty(PMV). The occluded artery could be detected by transfemoral carotid angiography and recanalized immediately by intra-arterial infusion of urokinase. There were no cerebral hemorrhage by CT scan after intra-arterial urokinase infusion and the patients discharged without any neurologic sequale 7 days after thrombolysis. We report a case of successful recanalization with intraarterial infusion of urokinase in patient with cerebral arterial embolism occurred during PMV.

PURPOSE: The purpose of this study was to describe the anglographic finding and clinical result of transarterial embolotherapy(TAE) in patients with injuries of renal artery branches by blunt trauma. MATERIALS AND METHODS: The study was based on retrospective analysis of seven cases, in which TAE was attempted for the control of traumatic renal arterial bleeding. All procedures were performed via the transfemoral approach. TAE was performed with stainless steel coil in two cases, Gelfoam in one case, and Gelfoam and stainless steel coil in four cases. RESULTS: Angiographic findings of vascular injuries were pseudoaneurysm in four cases, extravasation in two cases and arteriocalyceal fistula in one case. All procedures were performed successfully without complication. CONCLUSION: Pseudoaneurysm is a common anglographic finding in patients with injury of renal artery branches and TAE is considered a safe and effective method for treating such cases.

We report a case of myelodysplastic syndrome (MDS) with unique histopathological findings in which numerous infiltrated neutrophils exhibited nuclear segmentation anomalies. In comparison with well-described neutrophilic dermatoses of myelodysplastic syndrome such as Sweets syndrome and pyoderma gangrenosum, this case took a rapid and aggressive clinical course. We suggest that a nuclear segmentation anomaly, pseudo Pelger-Hiiet anomaly, is likely to reflect acute transformation of MDS and can be a poor prognostic marker.

We report a case of mycosis fungoides in a 28 year-old female patient who had multiple, bizzare, kidney or annular shaped, erythematous to brownishaly patches and plaques on the trunk, buttock, upper and lower extremities. Histopathologic finclingm showed epidermotropism and Pautrir microabscess in the epidermis and sssatypical lymphocytes infiltration in the dermis. T cell marker in leukocyte common antigen were positively stained in an immunohistochemical study. The skin lesions were reproved markedly after treatment it a total dose of 45 x 10 IU recombinant interferonaiv combination with a total dose of 385 iules/art PUVA.

A retrospective analysis was done on 68 patients with primary superficial bladder cancer between September 1989 and December 1995. We evaluated the predictive value of urine cytology in the recurrence and the progression of superficial bladder cancer. Positive cytology was shown in 52.9% (36/68) and was significantly associated with tumor grade (p=0.001). The recurrence rate in patients with negative cytology was 28.1% (9/32) compared to 77.8% (28/36) in those with positive cytology (p=0;001). No patients of negative cytology had tumor progression while 4 out of 36 (11.1%) patients of positive cytology had progression to invasive or metastatic disease. In conclusion, urinary cytology appears to be a significant prognostic factor in superficial bladder cancer.
