BACKGROUND
Pseudoaneurysm (PA) with associated arteriovenous fistula (AVF) is a rare delayed bleeding complication, occurring in less than 1% of patients after percutaneous nephrolithotomy (PNL). . A 54-year-old man underwent PNL on February 28, 2023, for a large renal calculus in the right kidney lower pole, with postoperative delayed bleeding: macroscopic hematuria and bladder clot retention after 3 weeks. An iatrogenic PA and AVF were diagnosed after the failure of conservative measures. The patient was successfully treated with superselective angioembolization (SAE) under local anesthesia.
CONCLUSION
Late hemorrhagic complications after PNL can be severe. Rapid identification of a renal PA and AVF with SAE has a high success rate and low complication rate, avoiding prolonged hospitalization time and major renal surgery for this patient.

Rats manifest a condition called hemorrhagic cystitis after spinal cord injury (SCI). The mechanism of this condition is unknown, but it is more severe in male rats than in female rats. We assessed the role of sex regarding hemorrhagic cystitis and pathological chronic changes in the bladder. We analyzed the urine of male and female Sprague-Dawley and Fischer 344 rats after experimental spinal cord contusion, including unstained microscopic inspections of the urine, differential white blood cell counts colored by the Wright stain, and total leukocyte counts using fluorescent nuclear stains. We examined bladder histological changes in acute and chronic phases of SCI, using principal component analysis (PCA) and clustered heatmaps of Pearson correlation coefficients to interpret how measured variables correlated with each other. Male rats showed a distinct pattern of macroscopic hematuria after spinal cord injury. They had higher numbers of red blood cells with significantly more leukocytes and neutrophils than female rats, particularly hypersegmented neutrophils. The histological examination of the bladders revealed a distinct line of apoptotic umbrella cells and disrupted bladder vessels early after SCI and progressive pathological changes in multiple bladder layers in the chronic phase. Multivariate analyses indicated immune cell infiltration in the bladder, especially hypersegmented neutrophils, that correlated with red blood cell counts in male rats. Our study highlights a hitherto unreported sex difference of hematuria and pathological changes in males and females' bladders after SCI, suggesting an important role of immune cell infiltration, especially neutrophils, in SCI-induced hemorrhagic cystitis.

BACKGROUND
Primary carcinosarcoma of the bladder is a rare and highly aggressive tumor, representing less than 1% of all bladder neoplasms. There is no specific treatment guideline has for carcinosarcoma of the bladder, and majority of published patients was treated exclusively by surgery.
CASE PRESENTATION
We report a case of 65-year-old Moroccan man, presented with macroscopic hematuria, pollakiuria and painful urination. Histological analysis showed a biphasic epithelial and mesenchymal proliferation, with invasion of lamina propria and muscularis, compatible with diagnosis of bladder carcinosarcoma. The patient was treated with cystectomy and adjuvant chemotherapy based on gemcitabin-cisplatin, 18 months after treatment, patient still free of recurrence.
CONCLUSION
Carcinosarcoma of the urinary bladder is a rare and aggressive tumor regardless treatment. A multidisciplinary management based on radical cystectomy and combined adjuvant treatments can improve prognosis. In this work, we suggest to propose adjuvant chemotherapy whenever possible.

Immunoglobulin A (IgA) nephropathy is the most common glomerular disease worldwide. It usually presents as a nephritic syndrome with macroscopic hematuria, oliguria, and proteinuria with or without azotemia. Rapidly progressive glomerulonephritis with crescents is being described in about 30% of cases and is mostly associated with nephrotic-range proteinuria, accelerated hypertension, and accelerated decline toward end-stage renal disease. Medullary angiitis is a rare finding in renal biopsy and is usually associated with pauci-immune glomerulonephritis. We describe a rare association of medullary angiitis in IgA nephropathy, probably the first reported case in the country.

INTRODUCTION
Urinary drainage is usually left in place after laparoscopic pyeloplasty to limit the risk of complications, such as urinary leakage. The procedure is sometimes laborious and complications may occur.
PURPOSE
Prospective evaluation of the Kirschner technique for urinary drainage during pediatric laparoscopic pyeloplasty.
STUDY DESIGN
This technique (Upasani et al., J Pediatr Urol 2018) involves introducing a nephrostomy tube (Blue Stent) with a Kirschner wire during laparoscopic transperitoneal pyeloplasty. We evaluated this technique by analyzing 14 consecutive pyeloplasties (53% on female patients, median age 10 years (6-16 years), on the right side in 40%) performed by a single operator between 2018 and 2021. The drain and urinary catheter were clamped and the perirenal drain removed on day 2. The stent was removed during consultation between days 7 and 15.
RESULTS
The median duration of surgery was 155 ± 7 min. Urinary drainage was installed within 5 min, without the need for radiological control and with no complications. All drains were correctly placed, with no drain migration or urinoma. Median hospital stay was 2 ± 1 days. One patient developed pyelonephritis (D8). The stent was removed without difficulty or complications. One patient presented an 8-mm lower calyx urinary stone at two months, revealed by macroscopic hematuria, necessitating extracorporeal shock wave lithotripsy.
DISCUSSION
The study design was based on a homogeneous series of patients, without comparison with another drainage technique or procedures performed by another operator. A comparison with other techniques might have been informative. Before this study, we tested various types of urinary drainage, to optimize performance. This technique was considered the simplest and least invasive.
CONCLUSION
External drain placement with this technique was rapid, safe, and reproducible in children. It also made it possible to test the tightness of the anastomosis and to avoid the need for anesthesia for drain removal.

Renal transplantation is a common treatment option for patients with end-stage renal disease. The goal of transplantation is to restore normal renal function and improve their quality of life. However, some patients may experience complications after transplantation, including the development of calculi or tumors in their native kidneys. In such cases, the question arises whether native nephrectomy should be performed during renal transplantation or not. A 62-year-old patient with a history of renal transplant twenty years ago presented a macroscopic hematuria.

Review
In kidney transplantation, a biopsy is currently the gold standard for monitoring the transplanted organ. However, this is far from an ideal screening method given its invasive nature and the discomfort it can cause the patient. Large-scale studies in renal transplantation show that approximately 1% of biopsies generate major complications, with a risk of macroscopic hematuria greater than 3.5%. It would not be until 2011 that a method to detect donor-derived cell-free DNA (dd-cfDNA) employing digital PCR was devised based on analyzing the differences in SNPs between the donor and recipient. In addition, since the initial validation studies were carried out at the specific moments in which rejection was suspected, there is still not a good understanding of how dd-cfDNA levels naturally evolve post-transplant. In addition, various factors, both in the recipient and the donor, can influence dd-cfDNA levels and cause increases in the levels of dd-cfDNA themselves without suspicion of rejection. All that glitters in this technology is not gold; therefore, in this article, we discuss the current state of clinical studies, the benefits, and disadvantages.

BACKGROUND
Nephroureterectomy remains the gold standard treatment for upper tract urothelial carcinoma (UTUC). Considering the high risk of developing renal function impairment after surgery, the rationale for nephron sparing approaches in treatment of UTUC has been raised. In this case, renal cryoablation was able to achieve successful oncologic control while preserving renal function during 5 years of follow up without intraoperative or post operative complications.
CASE PRESENTATION
A 79 year old male presents after three months of macroscopic hematuria. Imaging revealed a 3.6 × 3.1 × 2.7 cm endophytic mass in the interpolar region of the left kidney and an atrophic right kidney. After weighing the lesion's location with the patient's of complex medical history, he was counselled to undergo a minimally invasive percutaneous cryoablation as treatment for his solitary renal mass. A diagnostic dilemma was encountered as imaging suggested a diagnosis of renal cell carcinoma. However, the pre-ablation biopsy established an alternative diagnosis, revealing UTUC. Percutaneous cryoablation became an unorthodox treatment modality for the endophytic component of his UTUC followed by retrograde ureteroscopic laser fulguration. The patient was followed in 3 months, 6 months, then annually with cross sectional imaging by MRI, cystoscopy, urine cytology and renal function testing. After five years of follow-up, the patient did not encountered recurrence of UTUC or deterioration in renal function, thereby maintaining a stable eGFR.
CONCLUSION
Although evidence for nephron-sparing modalities for UTUC is mounting in recent literature, limited data still exists on cryotherapy as a line of treatment for urothelial carcinoma. We report successful management of a low-grade UTUC using cryoablation with the crucial aid of an initial renal biopsy and long-term follow-up. Our results provide insight into the role of cryoablation as a nephron-sparing approach for UTUC.

INTRODUCTION AND HYPOTHESIS
We aimed to examine the risk of bleeding in female patients undergoing intravesical onabotulinumtoxinA (BTX-A) treatments and provide clinical recommendations for the perioperative management of patients on antithrombotic therapy prior to BTX-A treatments.
METHODS
This was a retrospective cohort of Danish female patients, who had their first BTX-A treatment because of an overactive bladder at the Department of Gynecology and Obstetrics, Herlev and Gentofte University Hospital, between January 2015 and December 2020. Data extraction was from an electronic medical journal system. BTX-A, Botox® Allergan was injected in the detrusor at 10-20 sites. Significant bleeding during or after a BTX-A treatment was defined as persistent macroscopic hematuria. Bleeding reporting was based on information obtained from journal notes.
RESULTS
We included 400 female patients, who had a total of 1,059 BTX-A treatments. Median age at first BTX-A treatment was 70 years (IQR 21), and median number of BTX-A treatments was 2 (range 1-11). In total, 27.8% (n=111) received antithrombotic therapy. Within this group, 30.6% and 69.4% were on anticoagulant and antiplatelet therapy. No cases of hematuria were reported in our cohort. We found that no patients stopped their antithrombotic therapy, were bridged, or monitored by International Normalized Ration (INR) levels.
CONCLUSIONS
We suggest that BTX-A treatments might be classified as low-risk procedures. Discontinuation of antithrombotic therapy is not required in the perioperative management of this patient group.

Tuberous sclerosis (TS) is a multisystem neurocutaneous disorder with an autosomal dominant pattern of inheritance. It is characterized by hamartomas that damage the skin, kidneys, lungs, heart, and central nervous system, among other organs. Rhabdomyomas, benign tumors of aberrant myocytes, are common in affected patients at birth. Depending on their size and location, these lesions might create valvopathies, which can cause heart failure or malignant arrhythmias, or they can cause obstruction of the outlet or inlet tract. Before making the diagnosis, a long time-even years-often passes. Early diagnosis can help prevent permanent irreversible complications. Differential diagnoses may include neurofibromatosis type 1, Sturge-Weber syndrome, and von Hippel-Lindau disease, among others. Diagnostic aids, such as MRI, CT scans, and genetic testing, can be useful in confirming a diagnosis of TS. Histological findings may include the presence of hamartomas, which are benign tumors composed of abnormal cells. Treatment for TS is mainly supportive and may involve medications to manage symptoms, and surgery to remove tumors. We present the case of a 23-year-old woman with TS who was admitted with macroscopic hematuria and fever, with further workup revealing tumor-like cardiac lesions associated with infective endocarditis.
