Introduction: Renal pseudoaneurysms reportedly occur after partial nephrectomy, renal trauma, or percutaneous procedures. Renal pseudoaneurysms can also occur after renal inflammation; however, such cases are rare and seldom reported.
Case Presentation: A 53-year-old man presented to our emergency room with a 3-day history of fever and right back pain. A blood sample revealed severe inflammation and computed tomography showed an 8 mm diameter stone in the right middle ureter and hydronephrosis. The patient was diagnosed with calculous pyelonephritis and underwent emergency ureteral stenting and antibiotic therapy. On day 8 of hospitalization, hematuria and right back pain developed, and on day 9 bladder tamponade and anemia developed. Contrast-enhanced computed tomography revealed a ruptured pseudoaneurysm, and the patient underwent successful angioembolization. The patient was discharged on day 23.
Conclusion: We report a case of a renal pseudoaneurysm possibly caused by calculous pyelonephritis.

Aim: Calculous pyelonephritis is a severe infectious disease that predominantly affects the elderly population. However, there are few detailed reports on the stone formation process in calculous pyelonephritis. The purpose of this study was to investigate the process of calculous pyelonephritis formation and to identify markers of its onset.

Objectives: There are limited information that need to do appropriate treatment including duration of antibiotic treatments, timing of urinary drainage and pathogenesis of bacteria in calculous pyelonephritis. In the present study, we investigated real-world data on clinical features and succeeded treatment strategies in calculous pyelonephritis cases in our hospital, then, aimed to make predictive model estimating duration of intravenous antibiotics treatment.
Methods: Participants were 163 consecutive patients diagnosed with calculous pyelonephritis who underwent antibiotics treatments between 2017 and 2023 in our in-patients' clinic.
Difficulty in Removing a Ureteral Stent post Childbirth due to Encrustation: A Case Report.

Department of Urology, Nippon Medical School Hospital, Tokyo, Japan.
Background: We present a case involving a pregnant woman who needed transurethral lithotripsy for ureteral stent removal because of the stent encrustation.
Clinical Case: A 34-year-old woman was diagnosed with calculous pyelonephritis, and a double-loop ureteral stent was placed in her right ureter, after which the pyelonephritis resolved. One week after her delivery, we attempted to remove the ureteral stent; however, the encrustation of the proximal and distal coils made it impossible.

Urolithiasis in Russia still occupies one of the leading places in the total number of urological nosologies. Acute and chronic calculous pyelonephritis is the most severe complication of urolithiasis, causing destructive kidney damage in the form of apostematous pyelonephritis, abscess, kidney carbuncle and pionephrosis. In the case of acute obstruction of the urinary tract by concretion, purulent kidney damage occurs in a very short period of time and the result of treatment in this case depends on the adequacy and speed of the choice of the method of drainage of the urinary tract, that is, the elimination of their obstruction, as well as the correct choice of rational antibacterial therapy.
