1 Background

COVID-19 was declared as a pandemic by the WHO on 11 March 2020 [1]. As of December 2020, the total number of COVID-19 infected patients in India is more than ten million. Mumbai, the capital city of Maharashtra, is one of the most affected cities. Municipal Corporation of Greater Mumbai (MCGM) run tertiary care public hospitals includes King Edward Memorial Hospital (KEMH), Lokmanya Tilak Municipal General Hospital (LTMGH), and BYL Nair Charitable Hospital (Nair hospital). These have the busiest urology department in the state of Maharashtra where various urological services are provided. But since the lockdown, which was announced on 25 March 2020, these hospitals have been converted into COVID dedicated facilities to deal with the increasing number of COVID-19 patients. Urology wards were converted into medicine wards to accommodate COVID-19 patients. Since the beginning of lockdown, all elective outpatient clinics, elective indoor admissions, and elective operative procedures were suspended. As recommended by guidelines, only emergency patients were attended and emergency procedures were performed, which included patients with malignancy, haematuria, urosepsis, renal trauma, acute kidney injury, and complications of other specialities like obstetrics and gynaecology etc. [2, 3]. Despite lockdown, symptomatic patients presented in outdoor clinics and emergency departments and were attended.

Taking consideration of all the above factors, we compared the data of outdoor clinics, operation theatres, indoor admissions, during the COVID-19 pandemic with data of similar duration in pre-COVID-19 period and studied the impact of COVID-19 pandemic on non-COVID patient’s management in urology in Municipal Corporation of Greater Mumbai (MCGM) run tertiary care urology centres.

2 Methods

This is an observational study carried out during the period of lockdown from 1 April 2020 to 31 July 2020. Data of patients visiting the urology department in all the MCGM run tertiary care hospitals were recorded and compared to the data of the pre-COVID-19 period of similar duration. Data included indoor admissions and their indications, elective procedures, emergency procedures, and outpatient clinic attendance.

3 Results

3.1 Impact of COVID-19 on indoor admissions

Total indoor admissions during the COVID period were 82 as compared to 1337 in the pre-COVID-19 period of the same duration. There was a decrease of 93.86% in indoor admissions. Among admitted patients in urology wards, 62 (75.6%) were male and 20 (24.4%) were female. Mostly, the patients were in the age group of 51–60 years. The most common indication of admission was symptomatic renal or ureteric calculus disease and accounted for 44 (53.65%) admissions. Haematuria was the next common indication for indoor admission accounting for 13 (15.85%) admissions. Malignancy accounted for eight admissions (9.75%) (Figs. 1, 2, 3 and Tables 1, 2).

3.2 Impact of COVID-19 on emergency and semi-emergency procedures

There was a significant reduction in emergency and semi-emergency procedures performed during the lockdown. Procedures like cystoscopy and clot evacuation for haematuria, bilateral orchidectomy for metastatic carcinoma of the prostate, TRUS biopsy, catheter insertion had the highest cut-down, while procedures like DJ stenting, percutaneous nephrostomy insertion for AKI, infection and obstruction, DJ stent removal, and catheter change had less percentage decrease (Fig. 4 and Table 3).

3.3 Impact of COVID-19 on elective operations

There was a significant decrease in all types of elective urological surgeries. In particular, percutaneous nephrolithotomy, ureteroscopic lithotripsy, transurethral resection of the prostate, urethroplasty, and renal transplant had the highest cut-down. Instead of definitive elective procedures, DJ stenting and exchange were done in patients with renal and ureteric calculus disease with intractable pain, obstruction, and infection. Patients with BEP and urethral stricture were managed with perurethral catheter and suprapubic catheter change, respectively. Laparoscopic surgeries were strictly avoided due to the risk of transmission among healthcare workers (Fig. 5 and Table 4).

3.4 Presentations of patients in outpatient clinics

Previous outpatient attendance in these hospitals was approximately 3000 patients per month, which was reduced to 1260 patients during four months of the lockdown. Overall, there was more than 80% reduction in patients visiting outpatient clinics in public hospitals. Stone disease and its consequences were the main reason for visiting outdoor clinics (39%). A substantial number of patients presented with flank and abdominal pain (14.8%), benign enlargement of the prostate (10.23%), lower urinary tract symptoms (4.7%), and urinary tract infections (5.4%). Malignancy accounted for a very small number of patients visiting outdoor clinics (1.58%) (Figs. 6, 7 and Table 5).

4 Discussion

4.1 Effect on indoor admissions, operative procedures, and outpatient clinics

There was a significant decrease in the number of patients presenting to MCGM public healthcare set-up during the lockdown. The reasons attributed to lockdown, lack of transport, fear of coming to COVID-19 public hospitals, and negative image of public hospitals in local media. The majority of patients who came to hospitals were in the age group of 51 to 60 years and were at higher risk for complications if they got infected with COVID-19 [5]. Patients presented mainly due to complications arising from a benign condition. There was a reduction in patients with malignancy presenting in public hospitals. Malignancy accounted for only 9.7% of indoor admissions and 1.58% of the outpatient clinic visits.

There was a significant decrease in indoor admissions and elective operative procedures. As per guidelines issued by both the European Association of Urology (EAU) and the Urology Society of India (USI), stratification of various urological procedures was done. Elective operative procedures for renal and ureteric stones, benign enlargement of the prostate, urethral stricture disease, and renal transplant were affected the most [3, 4]. Semi-emergency procedures like percutaneous nephrostomy insertion, DJ stent insertion and exchange, DJ stent removal, and catheter change were less affected. Patients presenting with urological injuries related to obstetrics and gynaecological procedures had the least decrease in number as they were given priority for transport, diagnosis, and management. Studies done by Devana SK et al., Teoh JY et al., Prasad N et al. showed similar reductions in various urological procedures [6,7,8]. Similar findings were noted with regard to patients presenting to outpatient clinics. Stone disease and its complications remain the main reason for visiting outdoor clinics (39%). Substantial patients presented with flank and abdominal pain (14.8%), benign enlargement of the prostate (10.23%), lower urinary tract symptoms, urinary tract infections. Malignancy accounted for a very small number of patients visiting outdoor clinics (1.58%).

Our approach and management protocols changed because of COVID-19. Lei S et al. studied the patients undergoing surgeries during COVID-19 and concluded that there was 20% perioperative mortality in COVID-19 carriers and patients. So, there was a necessity to diagnose carriers of COVID-19 before surgery [9]. However, during the earlier period of lockdown nasal and throat swab RT-PCR and CT scan of the chest were not allowed for asymptomatic and planned operative urology patients due to the limited supply of testing kits. Patients with planned surgery were screened by checklist based on travel history, symptoms, and place of stay (zones), and those who were suspected of having COVID-19 underwent RT-PCR. This was the scenario till late June. Thereafter, RT-PCR and CT scan were easily available and used for screening of indoor patients with no or minimal symptoms of COVID-19 [10].

Most of the urology procedures were done in regional or local anaesthesia. General anaesthesia was avoided due to the risk of aerosol generation and transmission of COVID-19. OT protocols were changed, and donning and doffing areas were set up to reduce the risk of transmission to healthcare personal.

Most elective urological surgeries were postponed including endourological stone surgery, prostate surgeries, reconstructive surgeries, incontinence surgeries, infertility and erectile dysfunction surgeries, and genitourinary prolapse surgeries [11, 12]. Urinary diversion, treatment of sepsis, supportive treatment, and care were the cornerstone of management. Percutaneous nephrostomy and DJ stenting for the obstructive stone disease were initially attempted under local anaesthesia and if necessary regional or general anaesthesia was given. Acute urinary retention was managed by the insertion of a urethral or suprapubic catheter under local anaesthesia. In case of clot retention due to bladder cancer, prostate cancer, or benign enlargement of the prostate cystoscopy clot evacuation and haemostasis were performed. Definitive surgery was postponed for 2–3 months. Neoadjuvant chemotherapy was given to patients with malignancy as indicated. Patients who were scheduled for Radical Prostatectomy were given GnRH analogue. As per guidelines of EAU, BAUS, USANZ, radical prostatectomy for low-risk and intermediate-risk prostate cancer was postponed for 3 months. Children and patients with malignancy, trauma, obstetric, and gynaecological emergencies were given priority for treatment.

As per guidelines recommended by the Urology Society of India, laparoscopy and robotic procedures were avoided due to the risk of aerosol transmission [13, 14]. The live renal transplant program was temporarily suspended in all public hospitals as per MoHFW’s Advisory for Hospitals and Medical Institutions dated 03-03-2020 [15]. The long-term impact of delay in urological procedures will require further studies.

4.2 Effect on the training of residents

All urology residents were posted for COVID-19-related duties in rotation which affected the training of residents in routine and emergency urological surgeries. A nationwide survey of the impact of COVID-19 on urology residency in India by Cheriyan A. and Kumar S. concluded that there is a 90% reduction in caseload and surgical exposure leading to a negative impact on surgical training [16]. Effect on academic learning was less profound as online webinars and teaching sessions were increased as compared to pre-COVID era, and the writing of scientific project papers and textbooks was done more frequently.

5 Conclusions

COVID-19 pandemic has a profound impact on patient care and education in urology. There was more than ninety percent reduction in indoor admissions, operative procedures, and outpatient clinics attendance. Stone disease was the most common indication for indoor admission (53.65%) and outpatient clinic visits (39%). Malignancy accounted for 9.75% of indoor admissions and 1.58% of outpatient clinics visit. DJ stenting was the most common operative procedure performed. Once the pandemic is controlled, there will be a large number of patients seeking consultation and management for urological conditions and we should be prepared for it. Surgical training of urology residents needs to be compensated in near future. Long-term impact on urological patient outcome remains to be defined.
