Effects of first year COVID-19 pandemic on urology practice in three major Arab Countries: Sub-Analysis of a survey by Arab association of urology research group.

BACKGROUND AND OBJECTIVES: The World Health Organization (WHO) declared the coronavirus disease-19 (COVID-19) pandemic on March 11, 2020. The health care system faced tremendous challenges in providing ethical and high-quality care. The impact of COVID-19 on urological practices varied widely worldwide, including in Arab countries. This study aimed to compare the influence of the COVID-19 pandemic on urology practice in Egypt, the KSA, and the UAE during the first year of the pandemic. METHODS: This sub-analysis assessed the demographics and COVID-19's effects on urological practice in terms of adjustments to hospital policy, including outpatient consultations, the management of elective and urgent surgical cases, and the continuation of education across the three countries. The availability of personal protective equipment (PPE) and urologists' emotional, physical, and verbal intimidation during COVID-19 were also compared. RESULTS: Regarding the impact on hospital policy, consultations replaced by telemedicine were significantly higher in the KSA (36.15%), followed by the UAE (33.3%), then Egypt (10.4%) (P = 0.008). Elective cases requiring ICU admission were 65.1% in Egypt, 45.2% in the KSA, and 58.2% in the UAE and were performed only in high-risk patients. PPE was freely available in 20.8% of the Egyptian hospitals compared to 83.3% in the KSA and 81.8% in the UAE. Online courses were significantly higher in Egypt (70.8%), followed by the UAE (53%) and the KSA (41.7%) (P = 0.02). Emotional intimidation was higher than verbal intimidation, representing 80%, 75.9%, and 76% in the UAE, KSA, and Egypt, respectively. CONCLUSION: This sub-analysis outlined significant hospital policy changes across the three Arab countries. Exposure to emotional, verbal, and physical intimidation was observed. The development of teleconsultations and online platforms for educational purposes was observed.

Comparative study between antegrade flexible ureteroscopy and reterograde intrarenal surgery in the management of impacted upper ureteric stones 1.5 cm or larger.

OBJECTIVE: To prospectively investigate the safety and efficacy of antegrade flexible ureteroscopy (FURS) with the following criteria (supine, ultrasonic guided puncture through lower calyx with 14 fr tract, tubeless) versus retrograde intrarenal surgery (RIRS) in the management of large impacted upper ureteric stones ≥ 1.5 cm. PATIENTS AND METHODS: This study recruited 61 patients with single large impacted upper ureteric stone of ≥ 1.5 cm. The patients were randomly allocated to two groups. Group A, included 31 patients who treated by antegrade FURS, all patients were put in supine modified galadako Valdivia position and the renal access is reached by ultrasonic guided puncture through the lower calyx with dilatation upto 14 fr to insert ureteric access sheath and all cases were tubless with JJ stent insertion. Group B, included 30 patients who were treated by RIRS with JJ stent insertion. Stone fragmentation was done by holmium laser in both group. RESULTS: Group A was significantly associated with higher proportion of SFR (90.3%) compared to Group B (70%) (p = 0.046). Group B was significantly associated with shorter operative time and fluoroscopy time in comparison with Group A (p < 0.001). No significant differences were found between studied groups regarding bleeding (p = 0.238). Urosepsis showed significantly higher proportion associated with retrograde approach when compared to antegrade approach (p = 0.024). CONCLUSION: This study showed that antegrade FURS is safe and more effective than RIRS for the management of large impacted upper ureteric stones ≥ 1.5 cm.

Evaluation of ultrathin semirigid ureteroscopy in terms of efficiency and cost compared to flexible ureteroscopy in treating proximal ureteric stones: a prospective randomized multicenter study.

PURPOSE: To investigate the outcome and cost-effectiveness of ultrathin 6-7.5-Fr semirigid ureteroscopy in treating proximal ureteric stones compared to flexible ureteroscopy. METHODS: Two hundred and twenty patients with a solitary proximal ureteric stone were eligible for ureteroscopy (stone size = 1-2 cm). Patients were randomly subdivided into two groups: Group I included 105 patients who underwent ultrathin semirigid ureteroscopy and group II included 115 patients who underwent flexible ureteroscopy. Both groups were compared regarding successful stone access, operation time, reoperation rates, the financial cost to stone-free, complications, and stone clearance at 4 and 8 weeks. RESULTS: Groups I and II had no significant differences regarding patient demographics, stone criteria, and hospitalization time. In contrast, the mean operative time was significantly longer in group II (p < 0.001). The overall scope-to-stone access rate was 89.5%. It was 87.6% compared to 91.3% (p = 0.32), while the stone-free rate was 81.9% versus 87.8% (p = 0.22) for groups I and II, respectively. Intraoperative and postoperative complications were statistically insignificant between the study groups. The cost/person in Egyptian pounds was 8619 ± 350 in group I, compared to 17,620 ± 280 in group II (p < 0.001); similarly, the cost to attain the stone-free rate was 8950 ± 720 in group I compared to 17,950 ± 500 in group II. CONCLUSION: Ultrathin semirigid ureteroscopy is safe, durable, and considered a cost-effective method for treating upper ureteric calculi compared to the flexible ureteroscopy and could be considered a first treatment option in developing countries.

The effect of piezoelectric shockwave lithotripsy with 2- and 8-mm focus sizes on stone disintegration and renal injury.

OBJECTIVES: To compare the efficacy and safety of shockwave lithotripsy (SWL) using a narrow focus or wide focus for renal stones. PATIENTS AND METHODS: A double-blind randomised trial included adult patients with a solitary radio-opaque renal pelvic stone of 1-2 cm. Patients were randomised into two groups: narrow-focus (2 mm) SWL and wide-focus (8 mm) SWL. The stone-free rate (SFR) and presence of complications such as haematuria, fever, pain, and peri-renal haematoma were evaluated. Pre- and postoperative urinary markers (neutrophil gelatinase-associated lipocalin [NGAL] and kidney injury molecule 1 [KIM-1]) concentrations were compared to assess renal injury. RESULTS: A total of 135 patients were recruited for this study. The SFR after the first SWL session was 79.2% and 69.1% in narrow- and wide-focus groups, respectively. There was a comparable rise in the median 2-h NGAL concentration in both groups (P = 0.62). However, the rise in the median (interquartile range [IQR]) 2-h KIM-1 concentration was significantly higher in the narrow-focus group at 4.9 (4.6, 5.8) ng/mL compared with the wide-focus group at 4.4 (3.2, 5.7) ng/mL (P = 0.02). Nevertheless, the 3-day NGAL and KIM-1 urinary marker concentrations were significantly improved (P = 0.263 and P = 0.963, respectively). The overall SFR after three sessions was 86.6% and 86.8% in the narrow- and wide-focus groups, respectively (P = 0.77). Both groups were comparable for complications, apart from the median pain score and the percentage of high-grade haematuria, which were significantly higher in the narrow-focus group (P < 0.001 and P = 0.03, respectively). CONCLUSION: Narrow- and wide-focus SWL were associated with comparable outcomes and re-treatment rates. However, narrow-focus SWL was associated with significantly higher morbidity in terms of pain and haematuria.

How did the first year of the COVID-19 pandemic affect urology practice in Arab countries? A cross-sectional study by the Arab Association of Urology research group.

OBJECTIVE: The aim of this study was to assess of the effect of coronavirus disease 2019 (COVID-19) pandemic on urology practice in the Arab world during the first year of the crisis. METHODS: An Internet-based questionnaire was created and sent out via email to members of the Arab Association of Urology (AAU) using 'Google Forms'. The survey assessed participants' demographics in terms of age, gender, country of origin, type of practice and position. Impacts of COVID-19 on urological practice were assessed in terms of the changes in hospital policies regarding consultations, and elective and emergency surgical cases. Moreover, impacts of COVID-19 on urologists were assessed. RESULTS: A total of 255 AAU members across 14 Arab countries (Emirates, Egypt, Saudi Arabia, Iraq, Jordan, Algeria, Kuwait, Yemen, Qatar, Lebanon, Libya, Oman, Sudan and Syria) completed the survey; 4% were female urologists. Consultations at outpatient clinics were closed or restricted to emergency cases or replaced by telemedicine in almost 15%, 40% and 25% of hospitals, respectively. Elective surgeries were stopped or reduced to under 25% of surgical capacity in >10% and about 25% of hospitals, respectively. Almost 90% (228) reported changes in the policy for emergency theatres. Nearly 65% of hospitals offered preoperative COVID-19 testing to patients and 50% of hospitals provided personal protective equipment (PPE) to their urologists. Of 99% (253) who reported a change in urological education, 95% relied on online webinars. About 56% of respondents had their own private practice, of whom 91% continued private practice during the crisis. About 38% of participants reported exposure to intimidation (75% emotional, 20% verbal and 5% physical). CONCLUSION: The COVID-19 pandemic resulted in major changes in hospitals' policies regarding outpatient consultations, elective and emergency operative cases, and the shift to telemedicine. Arab urologists have been facing major challenges either in both the governmental or the private sectors, and some of them were exposed to emotional, verbal and even physical intimidation.

Transperineal intraprostatic injection of botulinum neurotoxin A vs transurethral resection of prostate for management of lower urinary tract symptoms secondary to benign prostate hyperplasia: A prospective randomised study.

Objectives: To evaluate transperineal intraprostatic injection of botulinum neurotoxin A (BoNT-A) in patients with lower urinary tract symptoms (LUTS) secondary to benign prostate hyperplasia (BPH) who failed to respond to 6-month medical treatment compared with transurethral resection of the prostate (TURP). Patients and methods: In all, 92 men were divided into TURP and BoNT-A groups after being evaluated using the International Prostate Symptom Score (IPSS) and five-item version of the International Index of Erectile Function, estimation of serum total prostate-specific antigen (tPSA), ultrasonographic estimation of prostatic volume (PV), and uroflowmetry determination of voiding volume (VV), maximum urinary flow rate (Qmax) and post-void residual urine volume (PVR). BoNT-A (200 U diluted in 3 mL saline) was injected, using a 22-G spinal needle under transrectal ultrasonography guidance, with 1-mL in each lobe. Patients were assessed 3-monthly for 12 months. Results: The IPSS significantly decreased in all patients with a non-significant difference between the groups. The mean VV and Qmax increased, whilst PVR, PV and serum tPSA significantly decreased. Patients who showed deterioration at 12 months were re-evaluated and underwent TURP. BoNT-A injection significantly maintained erectile function compared with TURP. Conclusion: Intraprostatic BoNT-A injection reduced PV with subsequent increases in VV and Qmax, and decreases in PVR and serum tPSA level. Intraprostatic BoNT-A injection allowed surgery sparing in >70% and preserved erectile function in 91.3% of patients. Abbreviations: BoNT-A: botulinum neurotoxin A; HRQOL: health-related quality of life; IIEF-5: five-item version of the International Index of Erectile Function; PV: prostatic volume; PVR: post-void residual urine volume; Qmax: maximum urinary flow rate; tPSA: total PSA; VV: voided volume.

Efficacy and safety of intradetrusor onabotulinumtoxinA injection for managing paediatric non-neurogenic overactive bladder: A prospective case-series study.

Objectives: To evaluate the outcome of intradetrusor onabotulinumtoxinA (Botox®; Allergan Inc., Dublin, Ireland) (IDB) injection in children and adolescents with non-neurogenic overactive bladder (OAB) refractory or resistant to treatment. Patients and Methods: In all, 91 patients underwent evaluation using subjective scores and urodynamic studies (UDS), including determination of maximum bladder capacity (MBC) and evaluating the capacity deficit vs the expected bladder capacity (EBC), and uroflowmetry determination of voided volume, maximum urinary flow rate (Qmax) and post-void residual urine volume (PVR). All patients received oxybutynin (0.3-0.5 mg/kg/day) for 3 months and re-evaluated patients who developed drug intolerability, persistence or recurrence of OAB received 100 U IDB injection using 20 injection sites, with trigone and sphincter sparing. All patients were re-evaluated 3-monthly for subjective scoring and at the end of the 12-month follow-up with UDS. Results: In all, 43 patients underwent IDB injection and at the end of the 12-month follow-up the success rate for IDB injection was 90.7%. All patients showed progressively decreasing scores compared to baseline scores. At the 12-month follow-up, MBC, voided volume, and Qmax were significantly higher, whilst capacity deficit and PVR were significantly lower than baseline measures. The frequency of patients satisfied with the outcome of IDB was high. Conclusion: For children with OAB refractory or resistant to biofeedback therapy, anti-cholinergic drugs must be tried first with IDB reserved for cases who fail to respond, are intolerant or recur after medical treatment. IDB using 100 U Botox, at 20 injection sites with trigone and sphincter sparing, is successful with a high satisfaction rate and free of postoperative problems.
