Clot Evacuation

Objective Urinary retention caused by bladder clots can be frustrating because such blood clots are difficult to remove. We established a novel technique in which hydrogen peroxide is applied to evacuate bladder clots. Methods In this single-center retrospective study, we evaluated 31 patients with retention of blood clots in the bladder who underwent emergency evacuation using hydrogen peroxide. Results The patients comprised 17 men and 14 women with mean age of 61.2 years (range, 42–82 years). Hydrogen peroxide solution and a 20-Fr three-cavity Foley catheter with large-diameter side holes were used for manual bladder irrigation in all patients. The bladder blood clots were successfully removed in 27 patients. The remaining four patients could not tolerate the symptoms of urinary retention and had to resort to surgery. Conclusion Hydrogen peroxide solution for manual bladder irrigation can improve the efficiency of bladder blood clot evacuation. This is a simple and effective option for managing bladder clot retention.

Introduction: We sought to provide a technical update on the use of a prostate morcellator device (PMD) to manage organized blood clots of the bladder following laser prostatectomy.Methods: Herein, we describe our experience in using the Wolf Piranha morcellator in managing organized bladder blood clots supplemented with a retrospective chart review of the patients in whom this procedure was performed.Results: Six patients, all male with a mean age of 75 ± 8.9 years, had organized bladder clots following either holmium laser enucleation or photoselective vaporization of the prostate managed with a PMD. Clots were recognized based on hematuria or urinary retention a median of 3.5 days following the aforementioned procedures. Initial management was attempted with more conservative measures, including a three-way Foley catheter, followed by cystoscopy with an Ellik evacuator, or a glass Tommey syringe. Morcellation times were a mean of 10.2 ± 6.15 minutes (range 2‒18). This technique was able to manage clots that were an average of 173.3 ± 115.9 cc in size. The procedure was well-tolerated. No patients experienced intraoperative or morcellator-related complications.Conclusions: Benign prostatic hypertrophy frequently requires surgical endoscopic management and can be complicated by hematuria and bladder blood clot formation. When these clots become organized, this can lead to urinary retention and the required management, evacuation, may be difficult. The use of a Wolf Piranha PMD is a safe, well-tolerated, and effective in evacuating organized blood clots of the bladder.

Background: Complications associated with oocyte retrieval include ovarian hyperstimulation syndrome, ovarian torsion, infection, bleeding, and even acute urinary retention. Case: A 29 year old female presented to the emergency department for dizziness and syncope following oocyte retrieval and was admitted for ovarian hyperstimulation syndrome. Her urinary catheter was obstructed by blood clots and relieved with bladder irrigated. The catheter was removed after twenty-four hours, and she was able to void spontaneously. Four days after discharge, she returned for urinary retention. She underwent cystoscopy and 10cc of blood clots was evacuated. The bladder appeared normal without intravesicular bleeding, and she was discharged home. Twelve hours later, the patient returned for urinary retention. Another cystoscopy was performed and 150cc of blood clots was evacuation. Her symptoms resolved. Conclusion: Hematuria and urinary retention are rare but serious complications of oocyte retrieval. Management options include a urinary catheter, bladder irrigation, urologic imaging, and cystoscopy

Objective: In this study we introduce using nasogatric tube as an alternative to procure a safe and efficient way to remove large troublesome blood clots during cystoscopy procedure. Material & methods: We prospectively perform blood clot evacuation using nasogastric tube suction (NGT) on 21 patients in Hasan Sadikin GeneralHospital Bandung,within 6 months period. A 24 fr sheath and 16 fr NGT connected to suction unit with a 300 mmhg negative pressure was set. A repetitive back and forth technique was set in motion during the procedure. Cystoscopy time and NGT suction time was documented. Results: All patients were successfully managed with this method without complication during the procedure. The average time for clot removal was 5 minutes 8 seconds with average cystoscopy time was 20 minutes 12 seconds and average estimated blood clots volume was 483 grams. Conclusion: Evacuation using NGT suction is effective, safe and an efficient way to remove a large bothersome clots.

Objective: Bladder rupture caused by transurethral clot evacuation is rare in clinic, but an emergency operation is indeed needed in the patient with bladder rupture. We analyzed the reasons of bladder rupture caused by transurethral clot evacuation and provided the countermeasures to guide clinical surgeon to prevent the iatrogenic damage of bladder. Method: We retrospectively reviewed the records of 287 patients in our hospital, who had bladder tamponade resulting from clots of blood for various reasons and underwent transurethral clot evacuation from January 2007 to January 2019. Six male cases, aged from 28 to 76 years (mean 56.67±17.76) had bladder rupture. Four patients whose bladder ruptured intraperitoneally were changed to open surgery to repair bladder and clear the remanent blood clots. Two patients with extraperitoneal bladder rupture and a small bladder crevasse underwent a conservative therapy. Results: We observed that the incidence rate of bladder rupture was not associated with bladder tamponade and the age, but may be associated with gender, bladder paracentesis preoperative and urinary retention preoperative. All six cases were male.. They had different period of urinary retention before operation. No supra-pubis bladder paracentesis was made before operation. The bladder crevasses located in the triangle zone and posterior wall of bladder entirely, and the length of the bladder crevasses ranged from 3 to 7cm (mean 4.83cm). The bladder crevasses were all lengthways, and four cases were of’ bladders ruptured intraperitoneally while another two presented an extraperitoneal bladder rupture. Conclusions: The reasons of bladder rupture caused by transurethral clot evacuation may be related to gender, bladder paracentesis preoperative and urinary retention preoperative. We should decide to use expectant treatment or open surgery immediately according to the extent of the rupture when bladder rupture occurs. doi: https://doi.org/10.12669/pjms.37.3.3911 How to cite this:Liu KL, Wang X, Qu CB, Qi JC.

The mechanism of the enzymatic iodination process of diethylmaleate and diethylfumarate (which present no miscibility with water) in the presence of lactoperoxidase, both in diluted hydrogen peroxide solution and in a generating system of hydrogen peroxide using ammonium and calcium iodides as halide sources in disperse system (after an ultrasonic pretreatment) was studied. The obtained sole product (diethyl-2, 3-diiodosuccinate) after the enzymatic iodination process was directly hydrolyzed to a tartaric acid present in an optically inactive form. The mechanism of obtaining the intermediate and final products and respectively, the existence of both D, L-tartaric acid and meso-tartaric acids (as lithium bitartrates) were also investigated.

This work demonstrates that the chlorinated antiseptics have no power to penetrate blood clots and destroy bacteria therein contained. Correspondingly, blood clots may protect virulent bacteria for a long period of time and the organisms properly planted will be able to proliferate in a normal manner.

Venous Gas Embolism

Gas embolism to the portal venous system is a well-recognized radiographic sign in infants with necrotizing enterocolitis. It also has been seen after colonic irrigation with hydrogen peroxide solution.1,2 We present what we believe is the first reported patient with radiographic evidence of portal venous gas embolism after ingestion of hydrogen peroxide solution. This finding is important because gas embolism to the portal venous system after colonic irrigation with hydrogen peroxide has been associated with gangrenous and perforated bowel.1,2 CASE REPORT A 2-year-old boy ingested an unknown amount of 3% hydrogen peroxide solution. The child was found with foam around his mouth.
