RESUMO
About 30% of all newly diagnosed renal cell carcinoma (RCC) patients present with synchronous metastatic disease. Usual organs of involvement are lung (75%), soft tissues (36%), bone (20%), liver (18%), cutaneous sites (8%), and central nervous system (8%). Metastases to the paranasal sinuses (PNS) are relatively common and may be a part of synchronous multiorgan involvement or present in follow-up after radical nephrectomy (metachronous); but primary presentation as isolated paranasal mass before the diagnosis of RCC is extremely rare. Here, we report a case of 74-year-old female presented with epistaxis and nasal obstruction. On evaluation by magnetic resonance imaging (MRI), a heterogeneously enhancing mass was found involving left PNS. Biopsy from mass revealed clear cell RCC. Later on, contrast-enhanced computed tomography (CECT) of chest, abdomen, and pelvis showed enhancing mass from the upper pole of the left kidney with no evidence of metastasis elsewhere. The patient was started on pazopanib 800 mg once a day. At 6 months follow-up scan, there was a partial response at both primary as well as metastatic site.
RESUMO
Introduction: Primary obstructed megaureter (POM) usually refers to primary dilated ureters in which vesicoureteral reflux and other secondary causes of lower ureteral obstruction have been ruled out. We herein present a case of obstructed megaureter with a dilated saccular lower end representing an ureterocele and concomitant multiple multifaceted stones almost completely filling the dilated tortuous ureter of a normally functioning and excreting kidney. Materials and Methods: Our index case was a 45-year-old lady with intermittent right flank pain for a year with acute colic since a week. Imaging revealed a grossly dilated tortuous ureter with >50 multifaceted stones all along its length, an ureterocele, and mild hydronephrosis. She underwent a robot-assisted ureterolithotomy and complete stone clearance followed by ureteral reimplantation over an ureteral stent. Results: Postoperative course was uneventful and on follow-up at 3 weeks, stent was removed after checking a cystogram. The da Vinci system with its minimally invasive approach and better ergonomics made it quite convenient to remove all 52 stones, ensuring an excellent postoperative recuperation and incomparable cosmesis. Conclusion: POM in adults is usually symptomatic and associated with complications, and surgery remains the mainstay of treatment when it is associated with calculi. Ureteral tailoring and ureteroneocystostomy with extraction of stones were done for at-risk kidneys and to prevent further renal deterioration. However, these efforts appear futile when the severe renal impairment has set in and nephroureterectomy is thus required. The robotic approach for reconstruction is a safe, effective, and feasible option with excellent perioperative results.
RESUMO
INTRODUCTION: Superior mesenteric artery (SMA) injury is very peculiar to left sided renal surgery. Although it is rare only, most of it is unreported. We report a case of SMA injury during robot assisted laparoscopic nephrectomy, which was managed successfully by end to end anastomosis. CASE PRESENTATION: A 19-year-old male patient was undergoing robot assisted laparoscopic simple nephrectomy for pyelonephritic kidney. Because of dense adhesion, SMA was inadvertently clipped and cut. It was recognised intraoperatively and an end to end anastomosis was done by laparotomy. DISCUSSION: SMA injury is rarely encountered in surgical practice. Most of it occurs following trauma. Iatrogenic SMA injury occurs in case of distorted local anatomy either due to adhesion or bulky tumor in left renal fossa and vicinity. CONCLUSION: One should be cautious about proximity of SMA and its possible injury during left nephrectomy and it should be repaired as soon as possible.
