Does intraoperative penile tourniquet application during hypospadias repair affect the patients and surgeons reported outcomes? A randomized controlled trial.

BACKGROUND: Hemostasis aimed to maintain the bloodless surgical field for better exposure for the surgeon. There are no trials regarding the impact of hemostasis techniques for hypospadias surgery on surgeon satisfaction and patients' reported outcomes. Application of penile tourniquet is a common practice in hypospadias surgery that aims at reducing blood loss and improving visualization. Yet, scarce data exist on the effect of penile tourniquet on hypospadias repair outcomes. PURPOSE: To evaluate the safety and efficacy of restraining penile perfusion using a tourniquet in hypospadias repair on the surgical outcome, also surgeons and patients reported outcomes. To evaluate the effect of penile tourniquet application on hypospadias repair outcome and surgeon's satisfaction with intraoperative hemostasis. STUDY DESIGN: In this single-blinded randomized controlled trial, a total of 110 children with distal hypospadias amenable for TIP repair were assigned to hypospadias repair with or without intraoperative application of a penile tourniquet. Surgeries were performed by a junior (2-5 years of experience in TIP repair) or a senior pediatric urologist (with >5 years of experience). Intraoperative blood loss, the number of times bipolar diathermy was used, hemoglobin deficit, and operative time were compared. Surgeon's satisfaction with intraoperative hemostasis was evaluated using a 4-tiered questionnaire. Patients were followed up for a minimum of one year. Complications and readmission rates were compared. The patient-reported outcome of hypospadias repair was assessed using the hypospadias objective scoring evaluation (HOSE). RESULTS: Baseline patient demographics and hypospadias characteristics were comparable between the study groups. Bipolar diathermy was more often used in the non-tourniquet group (mean ± SD = 5.7 ± 1.8 times vs. 6.7 ± 1.9 for the tourniquet group; p = 0.007). Also, the operative time was longer in non-tourniquet group [mean = 54.7 ± 14.9 vs. 60.8 ± 12.5 min (p = 0.028)]. Junior surgeons were more likely to be satisfied with hemostasis when a tourniquet was used (97.4% vs. 79.5%, p = 0.02). Postoperative complications, readmission rates, and patient-reported outcomes were similar between both groups. CONCLUSION: The application of penile tourniquet during hypospadias repair can reduce operative time and the need for diathermy use; and also improves junior surgeon's satisfaction with intraoperative hemostasis without adversely affecting success rates or patient-reported outcomes.

Holmium:YAG laser ureteroscopic lithotripsy for ureteric calculi in children: predictive factors for complications and success.

OBJECTIVES: To evaluate the impact of age, stone size, location, radiolucency, extraction of stone fragments, size of ureteroscope and presence and degree of hydronephrosis on the efficacy and safety of holmium:YAG (Ho:YAG) laser lithotripsy in the ureteroscopic treatment of ureteral stones in children. METHODS: Between October 2011 and May 2013, a total of 104 patients were managed using semirigid Ho:YAG ureterolithotripsy. Patient age, stone size and site, radiolucency, use of extraction devices, degree of hydronephrosis and size of ureteroscope were compared for operative time, success and complications. RESULTS: In all, 128 URS were done with a mean age of 4.7 years. The mean stones size was 11 mm. Success rate was 81.25 %. Causes of failure were 12.5 % access failure, 1.5 % extravasation and 4.7 % stone migration. Overall complications were 23.4 %. Failure of dilatation and extravasation were detected only in children <2 years old. Extravasation was significantly higher in smaller ureters and cases with stone size >15 mm. Stone migration was significantly higher in upper ureteric stones. CONCLUSIONS: Failure and complications rates in Ho:YAG ureterolithotripsy were significantly affected by younger age (<2 years), upper ureteric stones and smaller ureters but were not related to stone radiolucency or degree of hydronephrosis. Larger stones (>15 mm) were associated with increased complications. After multivariate analysis, the age of the patients remained significant predictor for failure of dilatation and stone migration, while size of the ureter was the only significant predicting factor for failure.

Renal pelvis reduction during dismembered pyeloplasty: is it necessary?

OBJECTIVE: To compare treatment results in patients who underwent pyeloplasty with and without pelvic reduction for ureteropelvic junction obstruction (UPJO). METHODS: This randomized prospective study involved 40 patients, all diagnosed with unilateral UPJO; 20 each were randomly selected to undergo open dismembered pyeloplasty with pelvic reduction (group A) or pelvis-sparing pyeloplasty (group B). Patients were evaluated with ultrasound and DPTA renography scans 6 months postoperatively. Mean follow-up was 9 months. RESULTS: The mean age in group B was 5.71 ± 6.36 years; in group A it was 4.81 ± 6.78 years. There was a decrease in mean anteroposterior renal pelvic diameter (from 49.9 to 26.35 ± 0.949 mm in A and 50.9 to 30.8 ± 1.556 mm in B) with improvement of split renal function (from 39 ± 22.47% to 42.4 ± 22.13% in A and 34.92 ± 16.79% to 38.8 ± 19.66% in B), glomerular filtration rate (from 37.25 ± 15.33 to 41.7 ± 19.34 ml/min in A and 31.3 ± 18.50 to 38.1 ± 23.23 ml/min in B) and draining curves on the 6-month scans, but without any significant difference between groups (p > 0.05). Two cases in group A and three in group B needed redo pyeloplasty, but without any significant difference in failure rate. CONCLUSION: Excision of the pelvis is not necessary in dismembered pyeloplasty procedures. We had similar surgical outcomes for patients with or without pelvis reduction.

Semi-rigid ureteroscopy for ureteric and renal pelvic calculi: Predictive factors for complications and success.

OBJECTIVE: To analyse and compare the effect of stone site and size, method of lithotripsy, and level of experience on the results and complications of semi-rigid ureteroscopy for ureteric and renal pelvic stones. PATIENTS AND METHODS: Between April 2010 and May 2011, 90 patients underwent 95 ureteroscopies, using 7.5- and 9-F semi-rigid ureteroscopes, with or without pneumatic or laser lithotripsy. The peri-operative findings were analysed and compared. RESULTS: The mean (SD) longest diameter of the stones was 11.8 (4.5) mm. Laser lithotripsy was used in 32 cases and pneumatic lithotripsy in 26. There were complications in 35 procedures in the form of colicky pain (2%), haematuria (1%), stone migration (7%), equipment failure (5%), access failure (8%), mucosal injury (7%), fever (2%) and extravasation (3%).The calculi were successfully retrieved in 75 patients (83%). The success rate was 95%, 77%, 85%, and 53% in the lower, middle, upper ureter and renal pelvis, respectively. CONCLUSIONS: Upper ureteric stones can be managed safely with the semi-rigid ureteroscope. Renal pelvic stones are associated with a lower success rate, and thus they were not a primary indication for ureteroscopic intervention. The secondary ureteroscopic management of renal pelvic stones improved the results of subsequent alkalinisation or shock-wave lithotripsy if they could not be eradicated completely. The failure rate was significantly small in lower ureteric stones and stones of <10 mm. Less experience, a stone size of >15 mm and patients ⩽2 years old were associated with more complications or a lower success rate. There was no significant difference in the success or complication rate between laser and pneumatic lithotripsy.

The effect of preoperative clinical variables on the 30- and 90-day morbidity and mortality after radical cystectomy: A single-centre study.

OBJECTIVE: To analyse the effect of preoperative clinical variables and comorbidity on the early, late and cumulative 90-day morbidity and mortality rates, as well as hospital re-admissions, after radical cystectomy (RC), in one centre. PATIENTS AND METHODS: All patients undergoing RC over a period of 3 months were included. Preoperative investigations included measurements of serum albumin, a complete blood analysis, body mass index (BMI), Charlson comorbidity index (CCI) and the age-adjusted CCI (ACCI). We recorded the length of hospital stay (LOS) and all postoperative events for 90 days, and graded them according to the five-grade modification of the original Clavien system. RESULTS: In all there were 31 patients undergoing RC (mean age 58.4 years). The mean preoperative serum albumin and haemoglobin level, BMI, CCI and ACCI were 3.82 g/dL, 12.53 g/dL, 29.29 kg/m(2), 3.0 and 4.58, respectively. The mean LOS was 20.03 days; seven patients needed re-admission and three died within the 90 days. There were postoperative complications in 20 patients. The age, CCI and ACCI were significantly associated with complications (P = 0.009, 0.001 and < 0.001, respectively). Preoperative haemoglobin, BMI and smoking had no effect on the morbidity or mortality rate. The LOS increased in older patients (P = 0.031) and those with a higher ACCI (P = 0.042). Postoperative mortality increased among patients with a lower serum albumin level (P = 0.048). CONCLUSIONS: Age, CCI and ACCI are related to early postoperative complications. Older patients and patients with a higher ACCI have a longer LOS. A low preoperative albumin level needs to be evaluated more thoroughly.

The expression of p63 in bladder cancer vs. chronic bilharzial bladder.

OBJECTIVE: To investigate the immunohistochemical expression of p63 in bladder cancer and the variation of expression in relation to histological type, grade and stage of the tumour, and whether bilharziasis (endemic in Egypt) has an effect on its expression, in an attempt to better understand the tumour behaviour and the possibility of using p63 as a prognostic marker. PATIENTS AND METHODS: In a prospective study, biopsies were taken from the bladders of 70 patients, who were divided into three groups; group A comprised 10 with a normal urothelium, group B comprised 20 with chronic cystitis (bilharzial and non-bilharzial) and group C contained 40 with bladder cancer. The biopsies were examined for the expression of p63, using immunohistochemical techniques. RESULTS: The mean (SD) ages of groups A, B and C were 45.2 (9.5), 50.5 (11.7) and 60.5 (9.9) years, respectively. There was a statistically significant decrease in the expression and immunoreactivity in group C (P < 0.05), and a significant decrease with advancing tumour stage and grade (P < 0.01). In cases of squamous cell carcinoma there was a statistically significant lower immunoreactivity than in transitional cell carcinoma (P < 0.05). There was a tendency for a statistically significant decrease in the immunoreactivity in bilharzial cystitis (P < 0.05), but in the malignant group, bilharziasis had no apparent effect on the pattern of expression. CONCLUSION: p63 might be a helpful biomarker and adjunct in predicting the biological behaviour and progression of tumours. Further studies are recommended to elucidate more clearly its role as a prognostic indicator and its utility as a tumour marker.
