Endoscopic intraluminal implantation of a self-expandable permanent urethral stent ( Wallstent) has found increased use in patient with recurrent urethral strictures because of its simple implantation technique. But there has been a few reports of explantation due to complete luminal obstruction. Herein we report one with literature.

PURPOSE: This study was designed to analyze the short-term clinical and functional outcomes of perineal rectosigmoidectomy with levatoroplasty for complete rectal prolapse. METHODS: The data were prospectively collected and consisted of the clinical data, the functional status before and after surgery, the operation record, and the postoperative course. The functional status was evaluated by using Wexner's constipation score (0-30), Wexner's incontinence score (0-20), anorectal manometry, and pudendal nerve terminal motor latency. Follow-up was performed at 3-6 months after the operation by using both a standardized questionnaire completed in the outpatient clinic or telephone interview (n=23) and an anorectal physiology test (n=7). RESULTS: During a one-year period, 23 patients (male=10) underwent perineal rectosigmoidectomy with levatoroplasty for complete rectal prolapse. The median duration of the operations was 88 minutes. The median length of postoperative hospital stay was 6 days. There was one urinary tract infection and no mortalities. The constipation score was significantly decreased after the operation (9.8 vs 3.8; P<0.001), and constipation was improved in 90 percent (19/21) of the cases. The incontinence score was significantly decreased after surgery (mean preop.=11.6, postop.=3.7; P<0.001) and incontinence was improved in 17 of 21 patients with impaired continence (81 percent). Anal sphincter function was not improved but rectal reservoir capacity was significantly decreased after surgery (rectal urgent volume (45.7 cc vs 37.1 cc; P=0.045), maximal tolerable volume (120 cc vs 85.7; P=0.011). Most patients (83 percent) felt that the operation had improved their symptoms. The major reasons for dissatisfaction after surgery were frequent defecation, fecal soiling, persistent or aggravated fecal incontinence, and recurrence. One patient had a complete recurrence (4.3 percent), and another patient had a mucosal prolapse which was treated. CONCLUSIONS: Perineal rectosigmoidectomy with levatoroplasty for complete rectal prolapse is a safe technique with acceptable short-term functional results; however, it is not recommended for rectal prolapse patients with diarrhea-predominant irritable bowel syndrome.

Two hundred thirteen urinary calculi were analyzed by X-ray diffraction method, which were obtained from the patients who were treated at the Department of Urology, Pusan National University Hospital from May 1989 to October 1993. The composition of our stone is classified to eleven. Pure stone was comprised 59.2 percents of all cases, and mixed stone was 40.8 percents of total. Calcium stone was 78.9 percents of all cases and non-calcium stone was 21.1 percents. Comparison with other clinics result using same study, the ratio of uric acid is significantly high. Calcium oxalate was the most common type in pure calculi( 83.3%) and mixed calcium oxalate and calcium phosphate calculi was the most common type in mixed calculi(52.9%) Calcium oxalate stone was the most common among the stones containing calcium, constituting 110(51.6%). Urate stone was the most common in non-calcium stone, constituting 24(11.3%) Ammonium acid urate containing stone was the largest in their size, uric acid stone was the smallest.

Benign fibrous polyps of ureter are rare. Recently, the rate of preoperative diagnosis and conservative management was progressively increased due to developed endoscopic procedures. Two additional cases of long, fibrous ureteral polyps, one with obstruction of contralateral ureteropelvic junction and the other with protruding mass to bladder, are reported with a brief review of literatures.

During the last decade, with the advent of prenatal ultrasound, multicystic dysplastic kidney is diagnosed with increasing frequency But the management of multicystic dysplastic kidney continues to be an ongoing controversy regarding both its cause and its current management. Herein we reviewed the records of four cases at our hospital between 1983-1993. All were unilateral and three cases were removed surgically and last one was observed and followed up only. The first case was a ten-month-old girl who was referred to our department because of hydronephrosis of kidney. The second was a five-year-old boy with chief complaints of flank pain. The third was a three-month-old girl, and the fourth was a two-day-old girl. Last two cases were referred to our department because of a sustained cystic dilatation of kidney detected by prenatal ultrasonography.

All of the methicillin-resistant Staphylococcus aureus (MRSA) strains exhibit resistance to oxacillin by producing PBP2a encoded by mecA, whereas methicllin-susceptible Staphylococcus aureus (MSSA) strains do not. To investigate phenotypic differences other than oxacillin resistance level in responses to oxacillin between MSSA and MRSA, we compared alterations of viability and ultrastructure of MSSA by oxacillin treatment with those of MRSA. When MSSA and MRSA strains were exposed to oxacillin of their respective MICs, and then were assayed for viability and observed by transmission electron microscope, increase in thickness of cell wall was more prominent in MRSA strains than in MSSA strains, while decrease in number of surviving cells was more evident and change in morphology of growing cross wall was greater in MSSA strains than in MRSA strains. It is assumed that these different responses to oxacillin between MSSA and MRSA strains may be due to activation of some PBP2a unbound to oxacillin. In conclusion, MSSA and MRSA showed different functional and morphological responses to oxacillin, although they were treated with oxacillin of concentrations that respectively inhibit their proliferation.
