The crossing laminar screw fixation might be the most recently developed approach among various fixation techniques for C2. The new construct has stability comparable to transarticular or transpedicular screw fixation without risk of vertebral artery injury. Quantitative anatomical studies about C2 vertebra suggest significant variation in the thickness of C2 lamina as well as cross sectional area of junction of lamina and spinous process. We present an elderly patient who underwent an occipito-cervical stabilization incorporating crossed C2 laminar screw fixation. We preoperatively recognized that she had low profiles of C2 lamina, and thus made a modification of trajectory for the inferiorly crossing screw. We introduce a simple modification of crossing C2 laminar screw technique to improve stability in patients with low laminar profiles.

We experienced two cases of giant hydronephrosis which contained 1,800, 1,200 cc of urine. It was caused by renal stone and congenital ureteropelvic junction stricture.

A clinical observation was made on 127 cases of gross hematuria who were admitted to the Department of Urology, Chosun University Hospital during the period from January, 1980 to October, 1982. The following results were obtained: 1. During the period, 127 cases (23. 1%) were found to be gross hematuria among 551 cases hospitalized. Of the 127 patients there were 95 males and 32 females, 3:1 in ratio. 2. The common diseases of gross hematuria were bladder tumor, renal injury, urethral injury tuberculosis of GUT, renal stone and ureteral stone. 3. Age distribution showed that 24 cases (18.9%) were 40-49 years, 21 cases (16.5%) were 20-29years and most frequent (67 %) ages were 20-59 years. 4. Etiology of the gross hematuria were highest in injury (34.6%), tumor (24.4 %) and calculus (18.9%). 5. The sites of the bleeding with gross hematuria were in the kidney (38.6%), bladder (30.0%), urethra (13.3 %), ureter (7.9 %), and prostate (4.7 %). 6. Incidence of painless and painful gross hematuria were 55.1% and 44.9%, the commonest cause was renal injury in the painless gross hematuria, urethral injury in the painful gross hematuria. 7. The incidence of initial, terminal and total gross hematuria were 4.7%, 22.1% and 73.2%. 8. The surgical treatment was required in 48 cases (37.8%) of inpatients with gross hematuria.

We reviewed the 46 cases of retrograde pyelography which performed in the Department of Urology, Chosun University Hospital during the period January 1981 to December 1982. And the results were as follows. 1. The cases were consisted of 23males and 23females. The most common age group was 40-49. 2. The common symptoms on admission were flank pain(50%) and gross hematuria(15.3%). 3. The urine findings(before RGP) revealed hematuria in 15 cases, pyuria in 12 cases, proteinuria in 5 cases and AFB positive in urine in 3 cases. 4. The IVP findings that were performed RGP classified into 4 groups as follows, 1) Abnormal changes or poor visualization of calyx, pelvis and ureter: 5 cases(10.8%) 2) Hydronephrosis: 13 cases(28.3%) 3) Delayed visualization: 18 cases(39.1%) 4) Non visualization: 10 cases(21.7%). 5. Of the 46 patients, most patients were defined with RGP and 24 cases had been required other special urologic studies for further evaluation.

Urethral mobilization is an adjunctive surgical technique for improving the position of the urethral meatus in a hypospadias operation. In our patient with mild degree of hypospadias and chordee the mobilized urethral meatus was placed out onto the glans without constructing a neourethra.
