Extracorporeal shock wave lithotripsy-induced renal laceration

Rupture of undiagnosed embryonal rhabdomyosarcoma after shock wave lithotripsy in an 11-year-old girl

We present a case of a rupture of an undiagnosed embryonal rhabdomyosarcoma after shock wave lithotripsy (SWL) in an 11-year-old girl. Although SWL is generally regarded as safe, careful imaging before SWL is important to prevent life-threatening complications in children.

Renal rupture following extracorporeal shockwave lithotripsy

A 41-year-old woman presented to the emergency department with a chief complaint of hematuria three days status post extracorporeal shockwave lithotripsy. The patient described a three-day history of worsening left-sided abdominal pain immediately following the procedure. She denied any fever, chills, changes in bowel habits, hematochezia, increased urinary frequency, urinary urgency, or dysuria.

Physical exam revealed tenderness to palpation in the left upper quadrant, left flank and periumbilical region with mild guarding. Laboratory studies revealed an anemic patient with downward trending hematocrit (red blood cell count of 3.41 10⁶/μL, hemoglobin of 10.6 g/dL, and a hematocrit of 31.3% down from 43% a week and a half prior). Urinalysis revealed red and cloudy urine with 3+ leukocytes.

A chest radiograph was unremarkable. A computed tomography of the chest, abdomen, and pelvis showed a laceration to the lateral aspect of the mid left kidney with a hematoma measuring 3.2 cm in thickness (Figure). The patient was subsequently admitted to the hospital for monitoring and discharged on day nine.

[Conservative treatment of severe renal trauma after extracorporeal shockwave lithotripsy]

Subcapsular and perinephric hematomas are relatively common after shock-wave lithotripsy, but high-grade kidney injuries are extremely rare. We present the first case of a high-grade kidney injury after shock-wave lithotripsy managed conservatively. A 57-year-old white female patient with left 1.5cm superior ureteral calculi was submitted to shock-wave lithotripsy.

Kidney rupture after extracorporeal shockwave lithotripsy: report of a case

BACKGROUND

Complications of extracorporeal shockwave lithotripsy (ESWL) occur in a small number of patients, although serious injury is rare.

OBJECTIVE

To report the serious complication of kidney rupture during ESWL.

CASE REPORT

A 65-year-old man was transferred to the Emergency Department (ED) with right flank pain. He had undergone ESWL for the right renal stone at a regional hospital 2 days earlier. Flank pain developed immediately after ESWL and was not spontaneously relieved. Computed tomography scan performed at the regional hospital showed an extensive right perinephric hematoma. When the patient arrived at the ED, his vital signs were unstable but were stabilized with fluid resuscitation and transfusion. Conservative care with no nephrectomy was chosen because there was no evidence of active bleeding on Doppler ultrasound examination. He was uneventfully discharged on the 31st hospital day without further complications.

CONCLUSION

Although it is rare, patients may present with kidney rupture or hypotension after ESWL.

Renal trauma

Urinary tract injury occurs in 10% of all abdominal trauma patients, and the kidney is the most commonly injured organ in the urinary tract. CT with contrast enhancement is the modality of choice for cross-sectional imaging of renal trauma because it quickly and accurately can demonstrate injury to the renal parenchyma, renal pedicles, and associated abdominal or retroperitoneal organs. This article reviews the mechanism, clinical features, imaging modalities, and CT imaging findings according to the classification of the renal trauma. Trauma to underlying abnormal kidneys, iatrogenic renal injuries, and complications of renal trauma are reviewed also.

Urological emergency: diagnosis and management of renal trauma

Renal trauma can be a life-threatening emergency and, because of its rarity, knowledge of its recognition and management is limited. This review discusses the clinical diagnosis, classification of injury, management and complications of this emergency condition.

Estimating the effectiveness of various methods of evacuation of kidney stones, on the basis of data obtained on percentage of "stone free" and recurrent stone formation

Using the materials of more than 200 scientific papers of recent years in this review it has been carried out analysis of the effectiveness and also discussed the merits and demerits of various methods of treatment of urinary stone diseases (USD). With this purpose, for the first time it has been carried out analysis of treatment quality of USD using more important quantitative parameters of treatment efficacy: 1--percentage of "stone free"; 2--percentage of recurrent stone formation. It has been emphasized on the higher effectiveness of treatment in combination of the method of ESWL with the methods of ascending litholysis. It was shown that in order to solve problems such as etiology and pathogenesis of the disease, elaboration of quantitative risk factors of the disease, and search for effective measures on pro- and metaphylaxis of USD, and also elaboration of various (including therapeutics) medium and methods for complete and rapid evacuation of stones, it is needed to carry out intensively fundamental and applied researches in the field of urinary stone diseases.
