The aim of this study is to evaluate efficacy as well as the predicting variables for successful early SWL patients with symptomatic ureteral stones. Eighty-six patients with a persistent renal colic secondary to single ureteral stone (6–12 mm) were prospectively enrolled in this study. SWL was performed within 24 h of the onset of flank pain. Pain control and stone-free rate after emergency SWL session were 58.1% and 44.2%, respectively. Seven patients required post-SWL ureteroscopy and ureteral stent placement for uncontrolled pain. The overall 3-month stone-free rate after SWL monotherapy was 83.7%. On multivariate analysis, predictors for pain relief after emergency SWL were lower Hounsfield (HU) stone density, mild hydronephrosis (HN) at presentation and presentation during the first colic episode. Lower HU stone density was the single predictor...

Controversies have been raised about considering the abdominal and inguinal ectopic testes as undescended ones. Our purpose was to review our center’s experience with the diagnosis and management of testicular ectopia focusing on the inguinal ectopic testis. Retrospectively, we studied the clinical and surgical characteristics of a case series of testicular ectopia which was managed in our center during July 2001–June 2016. Results Out of 1132 patients with undescended testes, 44 cases (3.9%) had testicular ectopia. Twenty-three cases (mean age = 5.15 ± 5.79 years) fulfilled the criteria of inguinal ectopic testis. Clinically, testes were relatively mobile and superficial. Surgically, they were located in the superficial inguinal pouch, had relatively long spermatic cords, and commonly had average rather than small sizes. T...

Retrospective search of our center data was done for the cases of long-standing urethral stones with normal urethra in male children during the period July 2001 - June 2016. Demographic and clinical data were studied. Of more than 54,000 urolithiasis procedures, 17 male children (0.031%) were operated for long-standing urethral stones with normal urethra. In 14 cases (82.4%), residence was rural and parental education levels were low or none. All children were regularly prompted voiding with a history of difficulty or dysuria. All the stones lodged in the posterior urethra with an approximate mean duration of 2 months. The mean stone size of 11.29 ± 3.88 mm and rough surfaces in 88.2% of cases represented the main predisposing factors. Major complications included rectal prolapse in 1 case and vesicoureteral reflux in 3 cases. Endoscopic push-back was follo...

Consecutive patients with isolated male epispadias treated in our center between 2008 and 2015 were classified into concealed and classic epispadias. The 2 groups were compared regarding age at presentation, meatal location, incontinence, dorsal curvature, success rate, and complications. Out of 51 patients with isolated male epispadias, 11 (21.6%) were concealed: 7 balanic and 4 penile shaft epispadias. Concealed epispadias cases were found to have significantly delayed age at presentation, more distal meatal location, and less incontinence rate than classic epispadias cases. None of the surgical outcome parameters showed significant difference between the 2 groups. Concealed epispadias represents about one-fifth of isolated male epispadias cases. Impediment and delay of diagnosis are its main clinical impacts, with insignificant effect on the surgical outcome.

MIP has proven its efficacy and safety in the management of small renal calculi. However, conventional PCNL is still considered the standard method for treatment of large renal stones in the upper urinary tract. A search of two longitudinal databases in two tertiary referral centres for complex stone disease identified 133 consecutive patients who were treated by either MIP or PCNL for renal stones 20 mm or larger between January 2009 and August 2012. Clinical data and outcome measures of the two methods were compared by Student's t test, chi-squared test or Fisher's exact test. A p value less than 0.05 was considered statistically significant. Operative time was significantly shorter and hospital stay was significantly longer in conventional PCNL compared to MIP (p = 0.002 and < 0.001, respectively). There were no significant differences in primary stone-free rate or complication rate between the two methods. Only higher graded complications (above Clavien grade II) were significantly more common in conventional PCNL (p = 0.02). MIP is equally effective as conventional PCNL in the treatment of large renal calculi. Both methods have a similar complication rate. The shorter operative time in PCNL may be based on the larger diameter and quicker retrieval of large fragments; the longer mean hospital stay may be caused by the handling of the nephrostomy tube. The current data suggest that the choice of the method mainly depends on the surgeon's preference.

From 2002 to 2011, 97 patients (72 men, 25 women, median age 65, range 42-84 years) underwent radical cystectomy with I-Pouch neobladder reconstruction. Complications were graded according to the Clavien-Dindo classification. Oncological and functional outcomes were assessed. The median oncological and functional follow-up was 41 months (range 3-107 months) and 18 months (3-111 months), respectively. In the total cohort, the 5 year cancer-specific survival was 67.9%. The major 30 and 90 day complication rates were 14.4% and 17.5%, respectively. Open reimplantation for ureterointestinal stricture was necessary in two (2.1%). Of the 95 functionally evaluable patients postoperatively, 93 urinated spontaneously (97.9%) and two patients (2.1%) required clean intermittent catheterization to empty their neobladder. The median postvoid residual urine volume (PVR) was 0 ml (range 0-200 ml). One patient had postoperative reflux (1%), as evidenced by voiding cystography. The median number of urinary tract infections per year was 0 (range 0-2) and showed no association with increased PVR (p = 0.18). The perioperative, oncological and functional outcomes of the I-Pouch are comparable to those of other types of ileal neobladder. An advantage of the I-Pouch is that the implantation of the ureters lies on the neobladder floor, which facilitates later instrumentation of the upper tract.

In this cross-sectional study, a total of 56 patients underwent radical cystectomy with ileal neobladder for bladder cancer [S-Pouch: 23 pat, 19 men, 4 women); I-Pouch: 33 pat (26 men, 7 women)]. They completed general (SF-36), cancer-specific (QLQ-C30) and bladder cancer-specific questionnaires (QLQ-BLM30) as well as a novel neobladder-specific questionnaire (TNQ). The questionnaire-based follow-up was 66 months (IQR 41-104; total range 9-161). I-Pouch patients reported better SF-36 physical health status (p = 0.026), QLQ-BLM30 continence scores (p < 0.001) and a more favorable QLQ-C30 total score compared to S-Pouch patients (p = 0.044). S-Pouch patients reported better QLQ-BLM30 general health status (p = 0.001). For the TNQ, no significant difference was found between both groups (p = 0.09). ...

METHODS: Of a total of 171 ileal neobladder procedures (I-pouch: 91 pat., S-pouch: 80 patients) performed in a tertiary academic center between 2002 and 2011 we evaluated QoL aspects in 61 patients (51 men, 12 women) who underwent radical cystectomy for bladder cancer. Thirty-three patients (26 men, 7 women) underwent an I-pouch and 28 (19 men, 9 women) an S-pouch procedure. The following questionnaires were used: the EORTC QLQ-C30, QLQBLM30 and the GIQLI (evaluating changes bowel habits). Additionally, we assessed the rate of vitamin B12 supplementation, bicarbonate substitution and recurrent urinary tract infections. Median follow-up was 66 months (IQR: 41-104; total range: 9-161. RESULTS: Median age at surgery was 68 (IQR: 43-84) in the I-Pouch and 66 years (IQR: 39-74) in the S-Pouch group (p 0.47). Patients with an I-pouch reported similar QLQ-C30 overall health status (median: 6, IQR: 4-6) compared to patients with an S-pouch (median: 5; IQR: 4-6; p 0.24). Patients with I-Pouch reported better QLQ-C30 QoL status (median: 6, IQR: 5-6) compared to patients with an S-Pouch (median 5, IQR: 4-6; p 0.037). Patients with an S-pouch reported better QLQ-BLM30 general health status (median 19, IQR: 11-26) compared to patients with an I-pouch (median: 29, IQR: 26-34; p 0.001). The median GIQLI score was 0.5 in patients with an I-pouch (IQR: 0-3) and 2 (IQR: 0.75-5) in patients with an S-pouch (p 0.11). Median number of recurrent UTIs was 0 (IQR: 0-2) in patients with an I-Pouch and 1 (IQR: 0-4) in patients with an S-pouch (p 0.036). Patients with an S-pouch tended to be on vitamin B12 substitution compared to I-pouch patients (p 0.07). No significant difference was noted with regard to the rate of bicarbonate substitution between both groups (p 0.57). CONCLUSIONS: In this long-term study, patients with an Ipouch experienced a lower rate of recurrent UTIs and tended to be at lower risk of vitamin B12 supplementation. These findings may be attributable to the reduced length of ileum used for the formation of the pouch. The heterogeneity of findings suggests that questionnaires, as the QLQ-C30 and -BLM30 are not valid enough to adequately address QoL aspects in patients with ileal neobladders. These data hint at the necessity to develop neobladder-specific questionnaires to adequately address QoL issues in different ileal neobladders.
