“…Percutaneous nephrostomy insertion and retrograde ureteric stenting have shown to have comparable success rates in obstructive uropathy secondary to urolithiasis; however, radiation exposure, length of stay in the hospital, and associated costs were higher in those with percutaneous nephrostomies when compared to ureteric stenting [7].…”

“…The insertion of a percutaneous nephrostomy or a ureteric stent is sometimes unavoidable in obstructive uropathy [7]. We present two cases of individuals who presented to a district general hospital within the National Health Service (NHS) in the United Kingdom, were treated for urosepsis secondary to an obstructing calculus, and were managed via the use of both antibiotics and the placement of a ureteric stent, done under local anesthesia at the bedside, for source control of the septic patient.…”

Sepsis is a life-threatening condition that needs the clinician to act quickly and swiftly in order to provide the best medical outcome for the patient. Sepsis can lead to multi-organ dysfunction, which is not only a risk to life but also utilizes multiple resources within the healthcare services. The management of any infection is reliant on two major factors: antimicrobial therapy and source control. We present two cases where source control, in the form of a ureteric stent insertion, was performed at bedside via the use of flexible cystoscopy to provide source control in the management of a septic patient.

“…UWT recently was proposed to predict failure of SWL, retrograde ureteral stent placement in addition to failure to manipulate stones during URS [ 12 , 13 , 17 , 18 ]. Increased UWT indicate the presence of impacted ureteral stones.…”

“…Increased UWT indicate the presence of impacted ureteral stones. Stone impaction occurred due to ureteral local inflammation, polyps and edema when stone fragments remain at the same location for a prolonged time period [ 18 ]. Yoshida et al, reported that measuring UWT by NCCT before starting treatment can be a good indicative marker for stone passage < 10 mm during MET [ 19 ].…”

Purpose We aimed to define factors affecting the non-invasive overall treatment success (medical expulsive therapy (MET) ± shock wave lithotripsy (SWL)) for uncomplicated ureteral steinstrasse (SS) clearance. Methods We retrospectively evaluated consecutive patients who underwent SWL for renal stones between 2017 and 2021. Patients with uncomplicated SS were included. All patient’s demographic and radiological data, e.g., age, gender, pre-SWL stenting, SS site, type, leading stone size in widest diameter (< 10 mm and ≥ 10 mm), ureteral wall thickness (UWT) in mm against the leading stone were collected. If SS was diagnosed, medical treatment was given for 4 weeks. In case of MET failure, either SWL for the leading stones + MET or direct URS was done. Non-invasive treatment success (SFR) was considered if complete clearance of SS occurred with no complications or the need for invasive intervention. Results A total of 145 patients were included with mean age of 45.9 ± 12.4 years. SFR in case of MET only occurred in 27.9%. Complications happened in 26 patients (17.9%). Non-invasive treatment SFR was achieved in 78 patients (53.8%) totally where SS type I, leading stone size ≤ 10 mm type and decreased UWT around the leading stone increased treatment success. Conclusion Ureteral wall thickness is an important factor predicting SS management success. Besides the decreased UWT, non-invasive management should be offered for type I SS with leading stone ≤ 10 mm.

Modern Methods of Treatment for Proximal Ureterolithiasis

Urolithiasis is a disease characterized by the formation of stones in the urinary tract. According to statistics, SCC causes about 30% of hospitalizations in the urology department. Treatment of SCC is divided into conservative and operative. The choice of method depends on age, clinical course of the disease, general condition of the patient, anatomical and functional condition of the kidneys and the size of the localization of the calculus. Methods of treatment of SC have changed significantly in recent years. Due to the technical achievements of the method of open ureterolithotomy, which was once the standard method of treatment of so-called «complicated» concretions of the ureter, evolved into a laparoscopic ureterolithotomy, and with the advent of ultrasonic and laser lithotriptors – began the newest era of minimally invasive urology– extracorporeal shock-wave lithotripsy and endourology: antegrade percutaneous ureterolithotripsy, retrograde ureteroscopic lithotripsy and flexible retrograde uretherolithotripsy (FURS). The purpose of the work – on the basis of scientific literature to assess the effectiveness, safety and profitability of modern methods of surgical treatment for proximal ureterolithiasis. During the scientific research, attention was paid to the following parameters: stone free rate (SFR), postoperative pain level, need for painkillers, number of postoperative bed-days, presence of postoperative fever, hemoglobin level, need for blood transfusion, and on the economic component during the implementation of a technique. The principles of treatment of patients with large proximal ureterolithiasis are described in the clinical guidelines of the European and American Associations of Urologists. However, for example, which of the 3 proposed methods of treatment of large proximal ureterolithiasis to choose – there is no consensus from the world urological community. Percutaneous antegrade ureterolithotripsy is the preferred method of choice in patients with large proximal ureteral stones that cannot be removed by contact or extracorporeal ureterolithotripsy, characterized by a high level of absence of stones and minimal complications, optimal post operative and high indicators of economic attractiveness of this technique.
