INTRODUCTIONUrolithiasis represents a major problem met within urological practice.1 it affects 10-12% of the populations, the incidence of calculus diseases is quite variable in relation to age, sex, occupation, geographical locations, season, climate, social class, dietary fluid intake and racial differences are also noted (black people appears to suffer less frequently than white). 2,3 Urinary calculi are the third most common affliction of the urinary tract, exceeded only by UTI and pathological conditions of prostate. 3Renal and ureteral calculi account for more than 87% of the total calculi and 10% in the urinary bladder while ureteral calculi account for about 1.7-3% of all urinary calculi. 5-7Male urethra about 20 cm in length and extends from the neck of the bladder to the external meatus on the glans penis, Male urethra is divided into posterior and anterior urethra, posterior urethra is further divided into 3 parts:• Preprostatic portion; measure up to 1 cm in length and it runs from the bladder neck to the prostate ABSTRACT Background: To evaluate the presentation, management and outcome of patient with urethral calculi in addition to determine the most common type of calculi encountered in those patients and the chemical composition of those calculi to prevent their recurrence. Methods: Sixty-nine patients with urethral calculi, 63 males and six females were included in this study at AlYarmouk teaching hospital, Bagdad, Iraq from April 2016 to April 2017. The diagnosis of urethral calculi was based mainly on the clinical presentation and cystoscopy evaluation in addition to the history, examination and investigations.Results: All together Sixty-nine patients were recruited in this study [63 male (91.3%) and 6 females (8.6%)], regarding sex distributions of patients the largest number of patients with urethral calculi were found in male between 21-40 years old, the most common presenting symptom was dysuria (60.8%), the presentation of pediatric urethral calculi was different (any suspicion of urethral mass on palpation gave high index of suspicion of urethral calculi). Conclusions: Nephrolithiasis especially renal calculi represent a widespread problem, recurrent UTI is one of the leading risk factor in urinary calculi and should be vigorously treated and any case should be in investigated carefully and chemically analysed to prevent further attacks and recurrence in future. Unbalanced diet with poor hygiene especially for the urethral calculi plays an additional role in the pathogenesis of urethra calculi.

BackgroundThis 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. MethodsBetween 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. ResultsNo 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±46.6 min; group 2, 33.0±13.7 min; and group 3, 24.6±8.0 min. 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. ConclusionNephroscopy 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.

“…In the work of Ener et al, 10 out of 43 patients needed urethrotomy before cystolitothripsy [ 13 ]. In addition, Ali et al had to make a bladder neck incision in 6 of 53 patients [ 14 ]. These maneuvers lengthened the operation time.…”

“…One of the commonly discussed aspects concerning cystolithotripsy is the risk of urethral injury, which is caused mostly by passing the cystoscope with a stone fragment through the urethra [ 14 ]. In our technique, the widest instrument inserted via the urethra is the 19F cystoscope, and this maneuver is performed only once at the beginning of the procedure.…”
