Male urethral diverticulum is uncommon lesion, furthermore calculus formation within the male urethral diverticulum is very rare. Generally, urethral diverticula are classified as congenital and acquired. The majority of male urethral diverticula are acquired and approximately 10 to 20 per cent are congenital. Acquired urethral diverticula in the male may arise from many sources, including infection(prostatic abscess, infection of periurethral glands, hematoma or schistosomiasis), obstruction (stricutre, impacted stone, Cunningham clamp or condom catheter) and trauma(instrumentation, external injury and pelvic fracture). Calculi formation is more common in the acquired diverticulum owing to stagnation of urine and infection. These calculi in the diverticulum usually are solitary and may attain considerable size with predisposing factors. 1) a ureteral or bladder calculus that is lodged in the urethra, 2) urethral trauma or stricture, 3) calcification around a foreign body or hair. The treatment of urethral diverticulum conbined with stone is excision of the diverticula with removal of stone. We treated two cases of urethral diverticulum combined with stone in the male, and report with review of literature.

A urinary calculus in the urethra is rarely seen and usually encountered in men with a urethral stricture or diverticulum. Herein, we report a rare case of a giant calculus in the urethra of a 42-year-old male patient with paraplegia after spinal cord injury due to car accident 20 years ago. A recent urologic consultation from the emergency room was performed since the patient had multidisciplinary symptoms during the day without any urination and presented with urinary difficulties due to hematuria and pain symptoms occurring with a mass in the bottom of the testicles. Abdomen and pelvic computed tomography (CT) was performed to examine the tumor mass, which was found to be absent. In addition, urethral stones were observed in the CT. Cystostomy was performed after the first urethroplasty, and the stone was removed from the urethra. Two weeks later, the patient was subjected to urethrography to remove the Foley catheter. No specific finding in voiding was detected. Giant urethral stones sometime require differentiation from tumor status. Treatment may vary according to size and location, requiring careful examination.

Background: This study compared the following three endoscopic techniques used to treat bladder stones: transurethral cystoscope used with a pneumatic lithoclast or nephroscope used with a pneumatic lithoclast and nephroscope used with an ultrasonic lithoclast. Methods: Between January 2013 and May 2016, 107 patients with bladder stones underwent endoscopic treatment. Patients were classified into three groups based on the endoscopic techniques and energy modalities used in each group as: group 1 (transurethral stone removal using a cystoscope with pneumatic lithoclast), group 2 (transurethral stone removal using a nephroscope with pneumatic lithoclast), and group 3 (transurethral stone removal using a nephroscope with ultrasonic lithoclast). Baseline and perioperative data were retrospectively compared between three groups. Results: No statistically significant intergroup differences were observed in age, sex ratio, and stone size. A statistically significant intergroup difference was observed in the operation time-group 1, $71.3{\pm}46.6min$; group 2, $33.0{\pm}13.7min$; and group 3, $24.6{\pm}8.0min$. All patients showed complete stone clearance. The number of urethral entries was higher in group 1 than in the other groups. Significant complications did not occur in any patient. Conclusion: Nephroscopy scores over cystoscopy for the removal of bladder stones with respect to operation time. Ultrasonic lithoclast is a safe and efficacious modality that scores over a pneumatic lithoclast with respect to the operation time.

Hypospadias is a rare congenital malformation of the urethra reported in cattle. The urethral lumen of male indigenous Korean calf is open along the ventral aspect of the penis in the perineal region. Renal abscess and renal stone formation causing urinary tact infection has not been reported in hypospadia calves. The objective of this study was investigation for renal abscess and renal stone formation through autopsy. Histopathological examination and laboratory tests were performed. At autopsy, the pustules were formed on the right renal cortex, and the renal medulla abscess were formed on right and left part of the renal pelvis. Histopathological finding, this case was diagnosed as severe acute suppurative and necrotizing pyelonephritis, and severe chronic interstitial nephritis with fibrosis and moderate multifocal acute cystitis with edema. Milky exudate of the kidney has been identified as Actinomyces meyeri using the VITEK-2 system for identification of bacteria, and the stone has been identified as carbonate apatite using FT-IR system for quantification analysis. This case report describe the hypospadias complicated with urinary tract infection due to carbonate apatite stones and Actinomyces meyeri.

Background: Persistent uroliths after a cystotomy in dogs are a common cause of surgical failure. Objectives: This study examined the following: the success rate of retrograde urohydropropulsion in male dogs using non-enhanced computed tomography (CT), whether the CT mean beam attenuation values in Hounsfield Units (mHU) measured in vivo could predict the urolithiasis composition and whether the selected reconstruction kernel may influence the measured mHU. Methods: All dogs and cats that presented with lower urinary tract uroliths and had a non-enhanced CT preceding surgery were included. In male dogs, CT was performed after retrograde urohydropropulsion to detect the remaining urethral calculi. The percentage and location of persistent calculi were recorded. The images were reconstructed using three kernels, from smooth to ultrasharp, and the calculi mHU were measured. Results: Sixty-five patients were included in the study. The success rate of retrograde urohydropropulsion in the 45 male dogs was 55.6% and 86.7% at the first and second attempts, respectively. The predominant components of the calculi were cystine (20), struvite (15), calcium oxalate (8), and urate (7). The convolution kernel influenced the mHU values (p < 0.05). The difference in mHU regarding the calculus composition was better assessed using the smoother kernel. A mHU greater than 1,000 HU was predictive of calcium oxalate calculi. Conclusions: Non-enhanced CT is useful for controlling the success of retrograde urohydropropulsion. The mHU could allow a prediction of the calculus composition, particularly for calcium oxalate, which may help determine the therapeutic strategy.

The effectiveness of Cefoperazone in the treatment of urinary tract infection was evaluated in the Department of Urology, St. Mary's hospital from December 1. 1979 to April 30. 1980. In this studies, the cusative organisms were divided into 2 groups; 1) Single form. E. coli (8), Staphylococcus aureus(7), Proteus vulgaris (4), P. morganii(3), S. epidermis (1), Enterococcus(1), Klebsiella (2), N. gonococcus(1). 2) Mixed from: Proteus+E. coli(4), E. coli+other(1), Pseudomonas+Enterococcus(1), Klebsiella+other(1). Effectiveness on urological diseases. 1) Neurogenic bladder: Results were excellent in 3 cases, good in 4 cases and negative effect in 4 cases. 2) Non-gonococcal urethritis: In this group, the therapeutic results were favorable in 88.9% of all cases. (Excellent in 2, Fail in1) 3) Pyelonephritis: All(4 cases) were excellent. 4) Renal stone: Among the 4 cases of renal stone, only one case was responded to cefoperazone. 5) Two cases of urethral stricture, two cases of cystitis, one case of B.P.H. and one case of gonococcal urethritis were all excellent. No serious side effects were observed except slight dizziness in one case.
