BackgroundSolitary fibrous tumor (SFT) is a rare soft tissue tumor originally reported in the pleura. Although it has been reported in various extra-pleural sites, the occurrence of SFT in the scrotum is extremely rare. Herein, we present a 48-year-old man who had scrotal SFT. There are very few reported cases of genitourinary SFTs, this is only the fifth report of SFT of the scrotum in the English medical literature.Case presentationIn this study, we report on a 48-year-old man who presented with a 5 × 8 cm scrotal mass between his testes. Physical examination revealed a 4.7 × 8.5 cm lobulated tumor mass located between his testicles. Surgical excision of the tumor with scrotal approach was done and pathology reported a SFT. The patient was alive without tumor recurrence or distant metastasis during ongoing follow-up for 9 months post-operatively..ConclusionScrotal SFTs are very rare and only five cases have been reported in English literature to date. Treatment often involves surgical resection, and a definite diagnosis is made with the help of immunohistochemistry. The current general consensus for the management of SFTs is long-term follow-up after surgical excision of the tumor.

Background Foreign bodies in the kidney have rarely been reported. However, they can be a clinical problem for urologists. We report on a patient with a residual segment of guidewire coating embedded in the renal parenchyma following computed tomography (CT)-guided percutaneous nephrostomy drainage (PCND), and our successful minimally invasive management with retrograde intrarenal surgery (RIRS). Case presentation A 40-year-old female with urosepsis due to a right upper ureteral stone with hydronephrosis received emergent CT-guided PCND and subsequent ureteroscopic lithotripsy, double J stent insertion, and percutaneous catheter removal. Follow-up radiography showed a coiled object within the upper pole parenchyma of the right kidney, which might be the remnant of a guidewire used during the PCND procedure. Flexible ureteroscopy (fURS) was performed. Under fluoroscopy, the foreign body was localized, the renal parenchyma was incised with laser, and the foreign body was retrieved using a stone basket. Conclusion Although guidewire breakage is uncommon, clinicians should keep it in mind during interventional procedures. Several methods can be used to eradicate foreign objects from the urinary tract, and the first choice should always be the least invasive one. RIRS with fURS is considered as a safe, efficient, and minimally invasive option for the extraction of foreign bodies from the kidney. To the best of our knowledge, this is the first comprehensive case report detailing the removal of a foreign object by RIRS in the English literature.

Case presentation In the current study, we report a 69-year-old female patient who was initially diagnosed with xanthogranulomatous pyelonephritis (XGPN) with nephrolithiasis and a peri-renal abscess. She presented to our department with right flank pain. Physical examination revealed right costovertebral angle knocking pain and computed tomography revealed dilated calyces and one staghorn stone over right kidney, with multiple abscess accumulations over the right peri-renal region. Right radical nephrectomy was performed using a transperitoneal flank approach, and pathology revealed squamous cell carcinoma (SCC) with concurrent XGPN. The patient was alive at 4 months post-operative follow-up. To the best of our knowledge, this is only the fifth case of renal SCC with concurrent XGPN reported in the English medical literature. Conclusion Renal SCC with coexisting XGPN is an extremely rare presentation and only four cases have been previously reported in the English medical literature. A positive diagnosis for this rare combination of diseases was established, based on pathological and immunohistochemical examinations after radical nephrectomy. Poor prognosis has been reported in such cases. Malignancies should be considered in patients with a long-standing history of urolithiasis.

Background: In this study, we aimed to compare the efficacy and clinical outcomes of shock wave lithotripsy (SWL) for patients with renal stones using pure fluoroscopy (FS) or ultrasound-assisted (USa) localization with two lithotripters.Methods: We retrospectively identified 425 patients with renal calculi who underwent SWL with either a LiteMed LM-9200 ELMA lithotripter (209 cases), which combined ultrasound and fluoroscopic stone targeting or a Medispec EM-1000 lithotripter machine (216 cases), which used fluoroscopy for stone localization and tracking. The patient demographic data, stone-free rates, stone disintegration rates, retreatment rates and complication rates were analyzed.Results: The USa group had a significantly higher overall stone-free rate (43.6 vs. 28.2%, p<0.001) and stone disintegration rate (85.6 vs. 64.3%, p<0.001), as well as a significantly lower retreatment rate (14.8 vs. 35.6%, p<0.001) and complication rate (1.9 vs. 5.5%, p=0.031) compared with the FS group. This superiority remained significant in the stone size <1cm stratified group. In the stone size >1cm group, the stone-free rate (32.4 vs. 17.8%, p=0.028), disintegration rate (89.2 vs. 54.8%, p=0.031) and retreatment rate (21.6 vs. 53.4%, p<0.001) were still significantly better in the USa group, however there was no significant difference in the complication rate. The most common complication was post-SWL-related flank pain.Conclusion: SWL is a safe and non-invasive way of treating renal stones. this study compared two electromagnetic shock wave machines with different stone tracking systems. LiteMed LM-9200 ELMA lithotripter, which combined ultrasound and fluoroscopic stone targeting outperformed Medispec EM-1000 lithotripter, which used fluoroscopy for stone localization and tracking, with better stone-free rates and disintegration rates, as well as lower retreatment rates and complications with possible reduced radiation exposure.
