Removal of Numerous Vesical Magnetic Beads with a Self-Made Magnetic Sheath

Abstract

Introduction Sexual curiosity and the quest for sexual excitement are the most frequent reasons for patients to introduce foreign bodies into the urethra or the bladder. Imagination and surgical skill are essential for urologists to retrieve such vesical foreign bodies. Aim The aim of this study was to describe a novel method for retrieving vesical magnetic beads, which were inserted for autoeroticism by a male adolescent, with a self-made “magnetic sheath.” Methods A 21-year-old young man inserted more than one hundred small magnetic beads into his urethra for sexual excitement, which lately caused symptoms of gross hematuria, frequent urination, and acute lower abdominal pain when walking or urinating. We invented a magnetic sheath by fixing a magnetic bead on the tip of an F9.5 ureteral access sheath to remove the foreign bodies in a minimally invasive way. Main Outcome Measure The feasibility of using magnetic sheath to remove vesical foreign bodies; and operation duration. Results Under direct visualization of an F8/9.8 ureteroscope, the magnetic sheath could firmly attach to the magnetic bead inside the bladder and could easily pull out 5 to 15 beads each time. It took about 5 minutes to remove all of the 125 magnetic beads by utilizing our magnetic sheath. Conclusions The self-made magnetic sheath can make the task of removal of magnetic foreign bodies easy to urologists, requiring less time and surgical skills. The new equipment provides a new method for urologists to deal with the challenging task of removing metal vesical foreign bodies which were self-inserted for masturbation.

The Practice of ‘Urethral Sounding’ Complicated by Retained Magnetic Beads Within the Bladder and Urethra: Diagnosis and Review of Management

“…Several medical case reports highlight the morbidity associated with this practice, most commonly when the sounding device, where an object has been used, can no longer be retrieved by the participant and requires urological review, often as an emergency. Diagnosis can usually be achieved by a plain radiograph; however, ultrasonography and CT imaging have been used [9,10].…”

“…Fourteen cases involving the insertion of magnetic beads into the urethra for the purpose of sexual stimulation have been reported since 2011 [9,11–13,15] (Table 1).…”

“…Rafique described 18 cases of intravesical foreign bodies, of which 8 were managed with successful endoscopic retrieval and 8 by open cystostomy, citing their only complications to be related to post-operative infective processes of the wound and urinary tract [3]. Pertaining only to the retrieval of magnetic beads within the bladder and urethra, approaches used reveal that 7 of 12 cases were successfully managed with various methods of endoscopic retrieval, 5 of 12 cases were managed with open cystotomy following failed attempt at endoscopic retrieval, and 1 case was managed first-line with open cystostomy [9,11–13,15]. One case was managed laparoscopically with an extraperitoneal approach to cystostomy and bladder closure following failed endoscopic approach [19].…”

Transurethraal inbrengen van magneetkralen voor seksuele stimulatie: twee patiënten

“…Robey et al beschreven een percutane cystotomie bij een 12-jarige jongen, bij wie met een nefroscoop eenvoudig 27 magneetkralen werden verwijderd met een paktang [8]. Zeng et al beschreven een alternatieve techniek voor endoscopische extractie van de magneetkralen, waarbij ze één 3mm-magneetkraal stevig hadden gefixeerd in het uiteinde van een F9,5-ureterale access sheath [9]. De patiënt werd in steensnedeligging geopereerd onder algehele anesthesie.…”

Removal of magnetic beads retained in small intestine by endoscopy combined with transnasal ileus catheter

“…3 Utilizing their magnetic properties has been documented as a successful tactic to removing magnets in the bladder and duodenum. Zeng et al 4 retrieved 125 magnetic beads in the bladder cystoscopically by using a home-made magnetic sheath (an ureteral access sheath with a magnetic bead on the tip), and another study 5 reported that a magnetic ball in a glove finger tied like a bag was inserted through the gastroscope to remove 18 magnetic beads in duodenum. However, the use of a transnasal ileus catheter has not been reported in this field.…”
