There was a development of the diagnostic aids such as electromyography, discography, epidural venography, myelography, and CT in lumbar disc herniation. In 1984, Edgardo et al. described that the diagnosis of unusual extreme lateral disc herniation might be suggested by CT, but the diagnosis was made more certain with CT done after discography. Also, in 1986, Michael et al. reported,that the addition of CT to lumbar discography could help the clinician to obtain an anatomically valid diagnosis in people who, in spite of prior negative diagnosis evaluation, continue with significant clinical symptoms of low back pain and sciatica. The authors have studied 25 cases of CT after discography from July 1984 to June 1987. The results were as follows;1) CT after discography, which was a diagnostic method of direct visualization of nucleus pulposus herniation, shown same finding as previous CT in 16 cases and more accurate finding of herniated site snd size in 2 cases. 2) In one csse, the diagnosis of extreme lateral disc herniation, which was suggested by previous CT, made more certain with CT after discography. 3) There was false negative in 6 cases.

PURPOSE: We have endeavored to find the factors predicting the success of ureteral stenting before cystoscopic retrograde ureteral catheterization in the patients with malignant ureteral obstruction. MATERIALS AND METHODS: 38 patients(51 kidneys) were analyzed, who were treated by retrograde ureteral stenting or percutaneous nephrostomy due to ureteral obstruction in non-urologic malignancy during the past 3 years. The sorts of primary tumors were cervix cancer in 14 cases(18 kidneys), stomach cancer in 12 cases(18 kidneys), colo-rectal cancer in 7 cases(9 kidneys), ovary cancer in 4 cases(5 kidneys), and endometrial cancer in 1 case(1 kidney). The cause of the ureteral obstruction was direct tumor invasion in 26 kidneys, lymphadenopathy in 23 kidneys and post radiation therapy in 2 kidneys. Retrograde ureteral stenting had failed in 22 kidneys(ureteral orifice could not be found in 14 kidneys, guide wire could not be advanced in 8 kidneys). RESULTS: Among the 51 kidneys, 29 kidneys(57%) were succeeded, and 22 kidneys(43%) were failed in retrograde ureteral catheterization. In fourteen of 22 kidneys(64%) ureteral orifice could not identified due to hemorrhage and edema of mucosa of bladder, and in 8 kidneys(36%) ureteral catheter could not be advanced to the renal pelvis. The cause of failure of the retrograde ureteral catheterization were direct tumor invasion in 10/26 kidneys(39%), and lymphnode enlargement in 4 of 23 kidneys(17%)(p=0.0007). According to the presence of ureteral obstructive symptoms, 8/29 kidneys(28%) were with the presence of ureteral obstruction symptoms, whereas 14/22 kidneys(64%) were failed with the absence of ureteral obstructive symptoms(p=0.0051). Of the obstruction site, 4/21 kidneys(19%) of upper to mid ureteral obstruction and 18/30 kidneys(79%) of lower ureteral obstruction were failed(p=0.0056). Of the degree of hydronephrosis, 18/47 kidneys(38%) of mild to moderate degree of hydronephrosis and 4/4 kidneys(100%) of severe hydronephrosis were failed(p=0.0022). CONCLUSIONS: This study shows that direct tumor invasion to the ureter, asymptomatic ureteral obstruction, lower ureteral obstruction, and high grade hydronephrosis were regarded as a high failure factors for the retrograde ureteral catheterization. Thus, we should not hesitate to choose percutaneous nephrostomy, in such condition that makes difficult for retrograde ureteral catheterization in malignant ureteral obstruction patients.

PURPOSE: We report our experience to assess the effectiveness and safety of Holmium:YAG laser lithotripsy for managing ureteral calculi. MATERIALS AND METHODS: Ureteroscopic Holmium:YAG laser lithotripsy was performed in 116 cases from November 1999 to October 2003. Calculi were located at the upper ureter in 9%, mid ureter in 19% and lower ureter in 72%. The mean stone size was 1.2cm. A 8Fr semirigid ureterorenoscope, 7.5Fr flexible ureterorenoscope and holmium:YAG laser (Trimedyne, Irvine, USA) with 365mul laser fiber were used. RESULTS: Stones were completely cleared in 113 cases among 116 cases. Stone-free rates according to stone position were 97.6% in the lower ureter, 100% in the mid ureter and 90.9% in the upper ureter. Stone-free rates according to stone size were 100%, 100% and 85.7% in the cases of which diameter is below 10mm, between 10mm and 15mm and above 15mm respectively. Fragmentation was incomplete in 3 cases, so ESWL was performed in 2 cases and repeated procedure in on case. Ureteral perforation was developed in 1 case. CONCLUSIONS: The Holmium:YAG laser lithotripsy was highly effective and safe in managing ureteral calculi irrespective of their location.

PURPOSE: In patient with grade III cystocele, to determine whether the anterior vaginal wall tissue, remnant at the anterior colporrhaphy, is an appropriate sling material, we retrospectively reviewed the outcomes of sling operations that used remnant anterior vaginal wall tissue. MATERIALS AND METHODS: An anterior colporrhaphy and sling operation using remnant vaginal wall tissue was undertaken in 21 patients. The preoperative evaluation included the patients' history, a physical examination, urinalysis, an urodynamic test, a voiding cystourethrogram and incontinence staging with Stamey grade. The surgical outcomes and stress- related leakage, emptying ability, anatomy, protection, inhibition (SEAPI) were assessed. RESULTS: The mean follow-up period, operation time and hospital stay were 18 months (12-36), 45.4 minutes and 8.6 days, respectively. 18 patients (85.7%) were cured and 3 (14.3%) improved. The total subjective SEAPI score of 8.48 decreased postoperatively to 1.78. The pre- and post-operative complications were unremarkable. CONCLUSIONS: The remnant anterior vaginal wall sling was helpful in minimizing the postoperative complications and cost effectiveness. Although long-term follow-up data might be required, this technique could be a good alternative method to replace conventional fascial or synthetic pubovaginal slings with grade III cystocele.

Midurethral slings are increasingly popular for the surgical treatment of stress urinary incontinence. They are relatively simple to implant and shorten operating time, hospital stay, and recovery time. Tension free vaginal tape (TVT) and Intravaginal slingplasty (IVS) mesh are both polypropylene mesh. TVT is a type I totally macroporous mesh which, because of pores larger than 75 microns, admits bacteria, macrophages, and fibroblasts into the pores. IVS is a type III mesh with microporous components which admits bacteria but not macrophages. So anterior IVS appear to be more at risk of infection or vaginal erosion than other monofilament mesh. We report our experience with a patient who underwent anterior IVS and developed erosion of the mesh through vagina, creating pelvic abscess.

Testicular granulosa cell tumor(GCT) is a rare neoplasm. We report here on an incidentally discovered testicular granulosa cell tumor in a 36-year-old man. The serum tumor markers were within the normal limits. The ultrasonographic findings revealed a mass with a heterogenous hypoechoic echotexture, including multiple variable sized cystic components. The histology on the orchiectomy specimen demonstrated a gonadal stromal tumor with granulosa cell features. Testicular granulosa cell tumor of the adult type is a very rare tumor, and there have been several isolated case reports and small serial studies described in the literature.
