PURPOSE: The placement of a ureteral stent following a ureteroscopy (URS) with a stone extraction is routine. However, many patients complain of stent pain and urinary symptoms in the postoperative period. Reducing the frequency of stenting would decrease the need for re-instrumentation, reduce costs, and increase patient satisfaction provided that the efficacy and safety are not compromised. In order to evaluate the necessity of stenting, a comparison of patients with and without stenting after URS for ureteral calculi is reported. MATERIALS AND METHODS: 45 patients with ureteral calculi amenable to ureteroscopic management were prospectively randomized into stented (23 patients) and unstented (22 patients) groups. Standard ureteroscopic basketing and lithotripsy were performed with a ureteroscope (8.5Fr) with or without ureteral dilatation. Postoperative symptom questionnaires were obtained from each patient. Radiographic follow-up to assess the stone-free rate and evidence of obstruction was performed in all patients. RESULTS: There was no statistically significant difference in the age, stone size, operation time, and hospital stay, between the unstented and stented groups (p>0.05). In addition, there was no statistically significant difference in the flank pain and urinary symptoms (p>0.05), except for hematuria between the 2 groups. Hematuria was more severe and long standing in the stent group (p=0.001). CONCLUSIONS: Uncomplicated ureteroscopy for calculus retrieval can safely be performed without the placement of a postoperative stent. Considering its complications and side effects, we do not believe that a routine placement of a ureteral stent following an uncomplicated ureteroscopy for a stone is necessary.

PURPOSE: Various endoscopic thyroidectomy procedures have been designed to minimize visible cervical scarring. However, endoscopic thyroidectomy is a technically challenging procedure that is performed by a limited surgeon. Robotic systems aida surgeon in performing minimally invasive head and neck surgery by offering superior visualization and dexterity. This study reports the initial experience of one surgeon with robotic thyroidectomy to assess the technical feasibility and safety of the approach. METHODS: One hundred four thyroid cancer patients (97 females, 7 males; mean age of 39.8±8.1 years) underwent robotic thyroidectomy using gasless transaxillary approach between November 2008 and October 2009 in Ajou University Hospital. All the procedures were completed successfully using the da Vinci surgical system without open conversion. Patient characteristics, postoperative clinical results, complications, and pathologic details were assessed. RESULTS: Total thyroidectomy was performed in 25 (24.0%) patients, subtotal thyroidectomy in 13 (12.5%) patients, and unilateral lobectomy in 66 (63.5%) patients. All patients underwent ipsilateral central compartment neck dissection, and two patients underwent selective lymph node (LN) dissection. The mean operation time was 134.5±47.2 min (range 61~310 min), in which the actual time for the thyroidectomy with lymphadenectomy (console time) was 56.4 min. (range 31~270). The mean number of LN resected was 3.9 (range 0~28). There were no serious complications. The mean hospital stay was 2.9±0.9 days (range 2~7). CONCLUSION: Robotic thyroidectomy is a feasible, safe, and cosmetically excellent procedure. The application of robotic technology for thyroid surgeries could be an alternative to endoscopic or conventional open thyroidectomy.

OBJECTIVE: Aneurysms arising from the posterior inferior cerebellar artery(PICA) are uncommon. We review literature on that and surgical results on aneurysmal treatment by choice of surgical approach. METHODS: On the basis of radiologic findings & charts, we review retrospectively the surgical results of 12 cases from Mar 1999 to Dec 2003. RESULTS: The mean age of the 12 patients was 55.8(ranged from 36 to 71) and female was predominant (female: male=8: 4). Locations of PICA aneurysms revealed variously(vertebral artery-PICA junction: 8, lateral medullary segment: 2, PICA-anterior inferior cerebellar artery common trunk: 1, telovelomedullary: 1). Surgical approaches & treatments were attempted in 11 cases and embolization was done in 1 case(Far lateral transcondylar or supracondylar approach & clipping: 9, Far lateral transcondylar or supracondylar approach and trapping: 2, suboccipital approach & clipping: 1). The surgical result were 8 of 12 patients were good outcome, 1 of 12 was severely disabled and 3 of 12 were died. CONCLUSION: First, we choose surgical approach by the laterality of aneurysms and surgical or interventional treatment is attempted as soon as possible. The PICA aneurysm is regarded as having a relatively good surgical outcome without drilling of the posterior arch of the atlas.

We had tried to perform mechanical aspiration using Hematoma and fibrinolytic drainage with Urokinase for treatment of spontaneous intracerebral hematoma(SICH) in 24 patients. Mean initial volume of SICH was 53.65+/-26.34 ml, mean evacuated amount of SICH after Hematoma procedure was 46.25+/-23.64%, and mean evacuated amount of SICH after fibrinolytic drainage after Urokinase was 74.15+/-20.89%, compared with pre-operative status. We could aspirate more than 50% of hematoma if the Hematoma procedure had been performed within 18 hours after ictus(p=0.0306). The rebleeding rate after Hematoma procedure was 8.3%, and overall mortality rate was 12.5%. There results seem to indicate mechanical aspiration using Hematoma and fibrinolytic drainage with Urokinase might be one of the useful method for treatment of SICH.

OBJECTIVES: To investigate if vitamin D receptor (VDR) gene polymorphisms and circulating vitamin D levels are associated with pelvic floor disorders (PFDs). METHODS: In this case-control study, 25-hydroxy-vitamin D (25[OH]D) serum levels were analyzed in 47 females with PFDs and 87 healthy females (controls), respectively. The VDR gene polymorphisms were determined by using polymerase chain reaction and performing digestions with 4 restriction enzymes i.e., ApaI, TaqI, FokI, and BsmI. Vitamin D levels of patients were divided into <20 ng/mL, 20 to 30 ng/mL, and ≥30 ng/mL categories. RESULTS: Our correlative analysis of VDR polymorphisms as a function of the presence of PFD showed that ApaI and BsmI polymorphisms were significantly associated with PFD in vitamin-D-deficiency and insufficiency groups (P < 0.05). Mean vitamin D levels did not differ between the PFD case (13.01 ± 0.84 ng/mL) and control (15.11 ± 1.04 ng/mL) groups (P > 0.05). However, there was a significant difference in the distribution of vitamin D levels between study group and controls using Pearson's χ2 test (<20 ng/mL, 20–30 ng/mL, and >30 ng/mL: 87.2%, 12.8%, and 0% in the study group and 75.9%, 16.1%, and 8.0% in controls, respectively, P < 0.05). Taken together, our observations suggest that vitamin D levels could be associated with PFDs and that 2 polymorphisms (i.e., ApaI and BsmI) in the VDR gene may contribute to an increased prevalence of PFDs in women with insufficient levels of vitamin D. CONCLUSIONS: Examining vitamin D levels and performing a VDR genotype analysis may be helpful for assessing PFD risk.

Canavan's disease is a hereditary disease that causes development delay by demyelinization of white matter in brain. The cardinal symptoms of Canavan's disease are head-lag, macrocephaly, developmental delay, blindness, epilepsy and hypotonia. Seven-month old baby delivered by Caesarean section at gestational age 40 weeks was complaining of an inability to keep head up. In past history, he was treated for congenital nystagmus. Chromosomal study was normal. Brain MRI showed delay of myelination of 5 months old. During neurodevelopment treatment in our hospital about development delay, macrocephaly was observed with head circumference 46 cm (90~97 percentile). He couldn't control his head yet. Brain MRI was done when he was 12-month old. There was no myelination in whole brain compared with that of same age group. The peak elevation of N-acetylaspartic acid (NAA) was showed in magnetic resonance spectroscopy (MRS). NAA was detected as high as 29.7 mmol/molCr, we diagnosed him as Canavan's disease. So we reported this case with a brief review of related literatures.
