RESUMO
BACKGROUND: Only a few cases have been reported about active foreign body implantation in the cavernous body of the penis. CASE PRESENTATION: A 47-year-old man inserted two needles from the glans penis into the bilateral penile sponge body. Subsequently, two needles migrated through the penile cavernous body into the pelvic cavity. Attempts to remove the needles through the penis were unsuccessful. Eventually, after a duration exceeding one month, the displaced needles were removed in stages from the buttocks. CONCLUSION: A few cases of intracavernosal-injection-therapy-associated needle breakage and retention have been reported globally. And this is the first case in China documenting the migration of foreign bodies within the penile region. In this condition, it is of utmost importance to engage the expertise of experienced andrologists to minimize the risk of excessive manipulation, thereby ensuring that inadvertent deep penetration of the needle into the penile tissue is prevented. In case the foreign body has migrated deeper into the tissues and the patient does not exhibit any specific symptoms or risks of macrovascular injury-related bleeding, close surveillance of its movement can be implemented. Surgical intervention can be initiated once the foreign body has reached a suitable position. Moreover, a psychiatric evaluation should be recommended for patient to discover any underlying mental health disorders.
RéSUMé: CONTEXTE: Seuls quelques cas ont été rapportés concernant l'implantation active d'un corps étranger dans le corps caverneux du pénis. PRéSENTATION DU CAS: Un homme de 47 ans a inséré deux aiguilles, par le gland du pénis, dans les corps spongieux du pénis. Par la suite, les deux aiguilles ont migré à travers le corps caverneux du pénis jusque dans la cavité pelvienne. Les tentatives pour retirer les aiguilles à travers le pénis ont été infructueuses. Finalement, après une durée de plus d'un mois, les aiguilles déplacées ont été retirées, par étapes, au niveau des fesses. CONCLUSION: Quelques cas de rupture et de rétention d'aiguille associés au traitement par injection intracaverneuse ont été signalés dans le monde. Il s'agit ici du premier cas en Chine qui documente la migration de corps étrangers dans la région du pénis. Dans cette situation, il est de la plus haute importance de faire appel à l'expertise d'andrologues expérimentés pour minimiser le risque de manipulation excessive, garantissant ainsi que la pénétration profonde par inadvertance de l'aiguille dans le tissu pénien est prévenue. Dans le cas où le corps étranger a migré plus profondément dans les tissus et que le patient ne présente pas de symptômes spécifiques ou de risques de saignements liés à une lésion macrovasculaire, une surveillance étroite du mouvement du corps étranger peut être mise en Åuvre. L'intervention chirurgicale peut être initiée une fois que le corps étranger a atteint une position appropriée. Enfin, une évaluation psychiatrique devrait être recommandée à la recherche de tout trouble sous-jacent de santé mentale.
RESUMO
INTRODUCTION: Upper urinary tract stones combined with parenchymal infiltrative renal pelvic cancer are challenging to detect on imaging and to evaluate the differential diagnosis. CASE PRESENTATION: The symptoms and diagnoses in three cases of parenchymal infiltrative renal pelvic cancer and upper urinary tract stones that occurred between June 2019 and June 2022 were reviewed. Primary symptoms of lumbar discomfort and hematuria were evident in all 3 patients. Preoperative computed tomography (CT) abdominal imaging revealed that all three cases had hydronephrosis along with renal stones, while the other two cases only had localized hypoenhancement of the renal parenchyma, which was only thought to be limited inflammatory changes in the renal cortex as a result of the combination of renal pelvis infection. After percutaneous nephrolithotomy or ureteroscopic lithotripsy, a combined renal pelvis tumor was discovered in all of these instances. Radical tumor surgery was later performed. One patient who had several tumor metastases passed away 6 months after surgery. A case with multiple metastases was discovered 15 months after surgery and survived with the help of the current chemotherapy. A case with a bladder tumor recurrence was discovered 16 months after surgery and had transurethral bladder tumor electrosurgery and routine bladder perfusion chemotherapy. CONCLUSION: Upper urinary tract stones and parenchymal infiltrative pyel carcinoma have atypical imaging, easily confused with infectious diseases. CT or computed tomography urography (CTU) must be considered by urologists. Patients who have a CT with local renal parenchyma density should be suspected of having parenchymal invasive renal pelvis carcinoma; a needle biopsy ought to be performed; and repeat biopsies may be performed if necessary. High-risk individuals need multiple, sufficient biopsies as needed and a comprehensive intraoperative assessment of the renal pelvic mucosa.
