Novel technique for the treatment of large subcapsular renal hematoma: combined use of percutaneous drainage and urokinase injection

Warfarin-ciprofloxacin interaction complicated by subcapsular renal hematoma and retroperitoneal hematoma: Case report

Spontaneous, non-traumatic bleeding into the subcapsular and perirenal space is a rare and potentially fatal condition known as Wunderlich syndrome (WS). It has a variety of causes including the usage of anticoagulation. Many anticoagulants including warfarin can interact with other medication and lead to potentially fatal complications, Herein, we report a case of a 47 year old female on warfarin who developed subcapsular renal hematoma and retroperitoneal hematoma after the completion of ciprofloxacin treatment course.

Case report: Ultrasound-guided percutaneous drainage combined with lavage using urokinase: An economical and effective treatment for muscular hematomas in hemophiliacs

This was an initial effort to treat hemophiliac hematoma by ultrasound-guided intratumoral drainage and lavage with urokinase after adequate supplementation of coagulation factors. Two patients with severe hemophilia underwent ultrasound-guided percutaneous drainage in combination with lavage using urokinase. After 5-day and 3-day treatments, respectively, intramuscular hematomas in both patients disappeared, compression symptom was relieved, and no obvious adverse reactions or serious complications were observed during the treatment or follow-up. These findings suggest that ultrasound-guided drainage combined with lavage using urokinase is an immediate, safe, effective, and minimally invasive treatment for intramuscular hematomas in hemophiliacs, avoiding potential complications by surgical resection with relatively low treatment cost.

Huge perinephric hematoma after ureteroscopy and pneumatic lithotripsy for ureteral stone; A life-threatening rare complication: Case report and review of literature

INTRODUCTION

Ureteroscopy with pneumatic lithotripsy is a relatively safe procedure for the management of the ureteral stone disease. However; subcapsular hematoma and even huge perinephric hematoma are potentially serious events that may complicate this procedure and must be kept in mind.

CASE PRESENTATION

We present a case of huge perinephric hematoma post ureteroscopy and pneumatic lithotripsy for an impacted ureteral stone.

CONCLUSION

The occurrence of such a rare complication in a relatively safe procedure must be taken into consideration especially while dealing with patients with long-standing obstruction and thin renal cortex. Furthermore, the risk of bleeding should be included in risk-benefit counselling before ureteroscopic lithotripsy.

Nephron-sparing management of Xanthogranulomatous pyelonephritis presenting as spontaneous renal hemorrhage: a case report and literature review

Background

Xanthogranulomatous pyelonephritis (XGP) is an uncommon infectious disease of the kidney known to mimic other renal maladies. A rare presentation of this uncommon disease is spontaneous renal hemorrhage (SRH).

Case presentation

We report a case of XGP in a 58 year old woman who presented with abdominal pain, hematuria, and radiating left flank pain. CT scan was felt to be consistent with perirenal hemorrhage abutting a fat-containing renal mass. The patient was eventually taken to surgery for left partial nephrectomy. Pathology report returned as XGP, and the patient has no complications from this disease process at 8 month follow up.

Conclusion

Our search of the literature shows XGP presenting as SRH to be a rare clinical entity. Furthermore, this is the first such case managed with a nephron-sparing approach. The “great imitator” XGP should be added to the differential for patients presenting with spontaneous renal hemorrhage.

Changing etiology and management patterns for spontaneous renal hemorrhage: a systematic review of contemporary series

OBJECTIVE

To conduct a systematic literature review on spontaneous renal hemorrhage (SRH) in a contemporary cohort describing patterns in etiology and treatment.

METHODS

A systematic search of MEDLINE and CENTRAL databases was conducted to include articles, including case reports and case series on SRH published from 2000 to 2016. Full-text manuscripts were reviewed for clinical parameters which were collated and analyzed with univariate methods.

RESULTS

Seventy-nine publications met inclusion criteria, reporting on 102 cases. Renal neoplasms (56.9%) and polyarteritis nodosa (PAN) (11.8%) remained as the most common overall and vascular causes of SRH, respectively. Angiomyolipoma (AML) was the most common causative renal neoplasm (74.1%), and patients were more likely to be female and present with macroscopic hematuria than those with vasculitis, while malignant neoplasms were more common in men. Proportions of SRH due to malignant neoplasms (specifically renal cell carcinoma, RCC) were reported less than PAN. Among this contemporary series, transarterial embolization (TAE) was most commonly used for acute SRH (42.2%).

CONCLUSIONS

Renal neoplasms remain as the most common cause of SRH, of which AML predominates, while PAN is currently the second most common etiology in acute SRH, replacing RCC. Minimally invasive approaches, such as TAE and conservative/medical management, were preferred to initial surgery.

Acute renal failure and arterial hypertension due to subcapsular haematoma: is percutaneous drainage a feasible treatment?

Percutaneous drainage proved to be successful in managing a renal subcapsular haematoma that was causing acute renal failure and hypertension in a 74-year-old woman. The patient presented with oliguria, nausea and malaise 2 days after a ureteronephroscopic procedure with biopsies of a suspected urothelial neoplasm in the right renal pelvis. The left kidney had recently been removed due to renal cell carcinoma. At admission, the patient's blood pressure and plasma creatinine levels were massively elevated. Ultrasonography revealed a moderate right-sided renal subcapsular haematoma. When the patient did not respond to antihypertensive treatment, Page kidney was suspected. A pigtail catheter was placed in the haematoma and, shortly after drainage, the diuresis resumed and plasma creatinine together with blood pressure decreased. This condition had previously been managed by open surgery, but recent case reports have described successful management by laparoscopy-assisted and radiology-assisted drainage, as described in this case report.

Sudden onset of a huge subcapsular renal hematoma following minimally invasive ureteroscopic holmium laser lithotripsy: A case report

The postoperative complication rate of ureteroscopic lithotripsy (URSL) is low, and the most frequent complication is fever. Thus, urological surgeons often neglect or are unaware of subcapsular renal hematoma (SRH) as a rare complication following URSL. Although a SRH after undergoing URSL is uncommon, the occurrence may be fatal. The current study reports on a rare life-threatening case that occurred recently at Zhongnan Hospital (Wuhan, China). A 24-year-old male patient presented with a large SRH (11×14×11 cm) after undergoing a failed, but minimally invasive URSL with a holmium laser. The presence of the large SRH was confirmed by computerized tomography imaging. The patient underwent conservative management, which prevented hematoma enlargement, and no further treatment was conducted. In conclusion, SRH, although rare following URSL, should be noted by the urological surgeon.
