The association of urethral stenosis and stones is not frequent. The urethral stenosis, particularly common in males, recognizes, as predisposing causes, urethritis, IPB, perineal trauma, neurogenic bladder and, last, but not the least important, endoscopic treatments or repeated catheterism. The authors report a case of a 42 year old man who underwent, for urolithiasis, several endoscopic examinations, which became urethral-stenosis with stones within four years. With responsible and critical behaviour, etiology, the diagnostic procedures and the therapy (invasive or not) of the urethral-stenosis are examined and evaluated. Diagnosis must be based on a non painful approach (clinical, bacteriological, ultrasonography, uro-dynamic studies); the invasive procedures must be limited as much is possible. Whatever treatment is used, which may always give sequences or complications, a prolonged follow-up is mandatory to have an objective evaluation of the results.

During a one-year morbidity survey of urinary tract diseases in general practice 741 cases were diagnosed. Only about half of all the patients with symptoms of urinary tract infection had significant bacteriuria. In young women urinary tract infections and symptoms from the urinary tract without bacteriuria-in particular urethritis-were found to predominate. In middle-aged women, the urinary tract symptoms were ascribed increasingly to genital prolapse, while incidence of urolithiasis was the highest in any group, and urinary tract infections became less frequent. The prevalence of urinary tract infection showed another increase in elderly women, and recurrent/chronic pyelonephritis, which occurs with a steadily increasing prevalence throughout all age groups, became common.In younger male urological patients diseases with symptoms of urinary tract infection without bacteriuria were predominant, whereas prostatitis and urinary tract infections were less frequent. In middle-aged men, urolithiasis was especially frequent, while an increasing proportion of elderly men had prostatic hypertrophy, urinary tract infections, and recurrent/chronic pyelonephritis.

A 14-month-old 40-kg Anglo-Nubian buck was referred for erection failure after recurrent bouts of obstructive urolithiasis. Previous episodes of obstructive urolithiasis were treated successfully with amputation of the urethral process, followed by an exploratory celiotomy and insertion of an indwelling Foley catheter into the bladder. The buck had been capable of intromission prior to the most recent episode of urethral obstruction. The results of physical examination and electroejaculation did not reveal any abnormalities, except failure to achieve erection. Contrast radiography of the corpus cavernosum penis (CCP), however, revealed failure of contrast media to migrate proximal to the sigmoid flexure. A diagnosis of obstruction of the CCP caused by cavernositis and fibrosis secondary to urolithiasis was made. A poor prognosis was given for breeding soundness. Although breeding soundness following obstructive urolithiasis may be enhanced by surgical intervention, impotence may result from obstruction of blood flow through the CCP secondary to urethral rupture or urethritis.

Massive urolithiasis of the penile urethra was observed in an adult pygmy sperm whale (Kogia breviceps) stranded on Topsail Island, North Carolina, USA. Calculi occupied the urethra from just distal to the sigmoid flexure to the tip of the penis for a length of 43 cm. A urethral diverticulum was present proximal to the calculi. The major portion of the multinodular urolith weighed 208 g and was 16 cm long x 3.7 cm diameter at the widest point. The urolith was composed of 100% struvite (magnesium ammonium phosphate) and on culture yielded Klebsiella oxytoca, a urease-positive bacterium occasionally associated with struvite urolith formation in domestic animals. Reaction to the calculi was characterized histologically by moderate multifocal to coalescing plasmacytic balanitis and penile urethritis. Role of the urethrolithiasis in the whale's stranding is speculative but could have involved pain or metabolic perturbations such as uremia or hyperammonemia.

According to the data of preventive medical examinations since the end of 2009 to April 2012, data on the urological incidence in 654 athletes surveyed during this period were collected and analyzed. Among the diseases identified in athletes, the main place is occupied by varicocele (5.35%), urethritis (5.04%), urolithiasis without clinical manifestation of acute inflammation (1.37%).

We sought to describe the incidence rate of the urologic disease in the Korean military by reviewing diagnoses made in active duty soldiers from 2008 to 2013. A total of 72,248 first visits were generated in the Defense Medical Statistics Information System (DMSIS) with its gradually increasing trend over 6 years. A sharp increase of first visit was observed after implementation of the regular health check-up for all conscripted soldiers since 2013. Urolithiasis, prostatitis, epididymoorchitis, urethritis, and varicocele were prevalent. Prostatitis was the highest diagnosis made in the outpatient service, while varicocele was ranked the highest in the inpatient service. The incidence rates of urologic disease varied from 12.3 to 34.2 cases per 1,000 person-years. The urologic disease in conscripted men showed different distribution when we separated the population into conscripted and professional soldiers. Epididymoorchitis was the highest disease followed by urolithiasis, dysuresia, and balanoposthitis in 2013. This study underscores that the urologic disease has spent significant amount of health care resources in the Korean military. This calls for further study to find any significant difference and contributing factors of the urologic disease in the military and the civilian population.
