In times of Covid-19 pandemic by reducing the hospital stay, patients have less contacts and it is more safe for them from an epidemiological point of view. The objective of our study is to evaluate the efficacy and safety of ESWL as a method of kidney desobstruction caused of ureteral calculi during Covid-19 pandemic. Material and methods: A retrospectively collected database of 77 patients, who underwent ESWL for ureteral stones between February 2020 and January 2022 in the Clinic of Endourology and SWL, Military Medical Academy, Sofia, Bulgaria, was reviewed. Data on patients’ preoperative characteristics, stone-free rates, complications and auxiliary procedures were analyzed. Results: Patients’ mean age was 49.1±12.8 years and male-to-female ratio – 75.3%/24.7%. Mean stone length was 6.5±2 mm and mean stone width was 4.5±1.5 mm. Fifty-two (n=52, 67.5%) of the cases were with stones located in the proximal ureter, in the middle ureter (n=14, 18.2%) and in the distal ureter (n=11, 14.3%). Preoperative drainage with ureteral stent was completed in 13 cases (16.9%). Mean hospital stay was 1.28 days Mean number of SWL hits was 3527±692. Full stone disintegration was observed in 55 patients (71.4%) and partial disintegration was observed in 22 patients (28.6%). Eight (36.4%) of the patients with partial disintegration of the stone needed another ESWL, in 2 (9%) people was performed RIRS afterward and 8 cases (36.4%) required performing an URS at a later stage. Conclusions: The ESWL as a method of treatment in ureteral calculi has good success rate. With the short hospital stay, it is an appropriate method for times of Covid-19 pandemic. However in some cases, invasive endourological operations such as ureteroscopy could not be avoided in order to be achieved full kidney desobstruction.

Saltirov","doi":"10.57045/jemis/1010722.pp25-32","DOIUrl":"https://doi.org/10.57045/jemis/1010722.pp25-32","url":null,"abstract":"Introduction: Anatomical features of the lower pole calyces plays an important role in the treatment of urolithiasis. The optimal treatment options for lower pole stones with a diameter below 2 cm are controversially discussed. Extracorporeal shock wave lithotripsy (SWL) is non-invasive, but is hampered by low stone-free rates and a significant retreatment rate in patients with unfavourable factors for lithotripsy. Retrograde intrarenal surgery (RIRS) has been demonstrated to have high stone-free rates since the development of modern flexible endoscopes. But the long operative time in the case of a large stone burden, unfavourable anatomy and considerable costs for consumables represent limiting factors for this technique. With the miniaturization of percutaneous approach and decreasing the morbidity, minimally invasive percutaneous nephrolithotomy (miniPCNL) is a promising method for treatment of lower pole stones in one stage procedure. The objective of this study is to investigate the efficacy and safety of mini-PCNL for the treatment of lower pole stones 1-2 cm. Material and methods: The medical records of 54 patients with lower pole kidney stones 1-2 cm, treated at the Clinic of Endurology and SWL, Military Medical Academy, Sofia between January 2020 to January 2022, were retrospectively reviewed. All patients underwent mini-PCNL under spinal anesthesia in prone position with fluoroscopic guidance through 18 Fr sheath using semirigid nephroscope and Ho:YAG laser for lithotripsy. Stone-free rate was defined as absence of residual fragments ≥2 mm. Data on patients’ preoperative characterstics, stone-free rates, operating times, intra- and postoperative complications were analyzed. Results: Patients mean age was 54,68±11,99 years. Mean stone surface was 169,02±57,40mm2 and mean CT stone density was 1112,26±250,47 HU. Stone-free rate after single procedure was 96,3 % (52 patients). 14,8% of patients had preoperative urinary tract infection. Mean operative time was 27,46±12,40 min and mean hospital stay - 2,5±1,17 days. The mean Hgb drop was 11.9±15.6 g/l. Lower pole puncture was performed in all patients. Two tracts were required in 1 (1,9 %) patient. One patient had intraoperative haemorrhage at the end of the procedure. Postoperative complications were observed in 2 (3,8 %) patients: postoperative fever t >38.5o C in 1 patient (1,9%) and postoperative AV-fistula in 1 (1,9%) patient, who needed hemotransfusion and selective embolization. 2 patients required auxiliary procedures: 1 patient needed stent JJ and 1 underwent ureteroscopy for fragments in ureter. Conclusion: Various factors are important for management of lower pole kidney stones and should be taken into consideration, when choosing the optimal treatment modality. The results from this study suggest that mini-PCNL is an effective and safe procedure with high stone free rates and low complication rates in patients with lower pole kidney stones unfavourable for SWL and RIRS.

With the onset of the COVID-19 pandemic leading to the temporary suspension of elective surgical activity, emergency ureteroscopy has become a valuable modality for the treatment of acute renal obstruction. The objective of this study is to evaluate the efficacy and safety of emergency ureteroscopy as first-line treatment for patients with acute renal obstruction due to ureteral stones during the COVID-19 pandemic. Material and methods: A prospectively collected database of 120 patients with acute renal obstruction due to ureteral stone who underwent emergency ureteroscopy within 24 hours from hospitalization between March 2020 and December 2021, was reviewed. Data on patients’ preoperative characteristics, stone-free rates and complication rates was analyzed. Results: Patients’ mean age was 51.4±15.2 years. Male-to-female ratio was 73.3%/26.7%. Mean preoperative serum creatinine values were 120.1±64.1 umol/l. 33 patients (2.5%) had a solitary functioning kidney. Stone location was proximal ureter in 3 patients (27.5%), mid-ureter – in 12 (10%), distal ureter – in 73 (60.8%), distal and proximal ureter – in 2 cases (1.6%). Mean stone size was 8.1±3.3 mm. Stone-free rate after a single procedure was 95% and mean operative time – 25.1±11.5 min. Postoperative drainage was stent JJ in 34 (28.3%) and ureteral catheter for 12h – in 22 (18.3%) patients. 21 patients (17.5%) had a narrow ureter, necessitating the use of smaller caliber ureteroscope (6 Fr). In 2 patients (1.7%) the ureter could not be accessed and a stent JJ was inserted. Intraoperative complications were present in 5 cases – 1 ureteral perforation (0.8%) and 4 cases of upward stone migration (3.3%). Postoperative complications were fever in 2 patients (1.7%) and postoperative renal colic pain - in 7 (5.8%).

It is associated with higher pain score than the other methods of prostate biopsy. Effective analgesia is a key point for providing patient comfort and preventing his movement in response to pain with subsequent mismatch of the fused MRI/ US images. The mismatch could lead to inaccurate targeting of suspected cancer lesions. The preferred method of analgesia in an outpatient setting is topical intrarectal administration of lidocaine and periprostatic nerve block, but the pain and the discomfort from the procedure are not completely eliminated. Hypothetically, saddle block anesthesia has an expected better efficacy in relieving the pain from the MRI/US-TPB. Aim: To evaluate the efficacy and safety of saddle block anesthesia in patients undergoing MRI/US-TPB and сomparative analysis between patients who have received and have not received intravenous fentanyl Material and methods: A prospective randomized study was conducted on 12 consecutive patients undergoing MRI/US-TPB. Saddle block anesthesia was performed with 20 mg prilocaine hydrochloride 2% hyperbaric solution to all patients. 6 patients received intravenous fentanyl at a dose of 1mcg/kg (Group 1) and 6 patients did not receive intravenous fentanyl. It was examined: patient’s age, weight, height, BMI and ASA class; duration from the dural puncture to the end of the surgical intervention; taken number of prostate biopsies; presence of intraoperative pain; motor blockage; presence of a difference of more than 20%, before and after saddle block anesthesia, of non-invasively measured blood pressure and heart rate; additional medication; presence of early postoperative complications and recovery time from anesthesia Results: The comparative analysis of the preoperative characteristics of the both groups did not reveal significant statistical difference. There were comparatively similar indicators for surgical intervention and regional anesthesia in both groups. The both anesthesia techniques showed safety profile with hemodynamic stability, without additional medicine administration and lack of early post-anesthesia complications. Pain did not occur during inserting and moving the US probe into the anal canal and puncturing the perineal skin and the underlying tissues. 50% (3) of the patients in Group 2 had pain during the puncture of the prostate gland and biopsy extraction, while in Group 1 - 0% (0) of the patients reported presence of pain. There was a slightly delayed onset of the first postoperative pain in Group 1 - 113.17 ± 15.11 min. compared to Group 2 - 99.83 ± 11.51 min.
