ABSTRACT

In Australia, approximately 3 % of all cancers diagnosed each year are renal cancers. Renal Cell Carcinoma (RCC) represents 90 % of all primary renal malignancies. RCC are slow growing and often asymptomatic, thus are often found incidentally. Here we present the case of a 76-year-old male who was found to have a metastatic RCC in a para-aortic lymph node with no primary lesion. He underwent a retroperitoneal lymphadenectomy and 15 months after the surgery, has had no signs of primary tumours or metastasis. This case reports on a rare instance of metastatic RCC without an identified primary renal malignancy.

ABSTRACT

INTRODUCTION: Demand for donor kidneys far exceeds the availability of organs from deceased donors. Living donor kidneys are an important part of addressing this shortfall, and laparoscopic nephrectomy is an important strategy to reduce donor morbidity and increase the acceptability of living donation. AIM: To retrospectively review the intraoperative and postoperative safety, technique, and outcomes of patients undergoing donor nephrectomy at a single tertiary hospital in Sydney, Australia. METHOD: Retrospective capture and analysis of clinical, demographic, and operative data for all living donor nephrectomies performed between 2007 and 2022 at a single University Hospital in Sydney, Australia. RESULTS: Four hundred and seventy-two donor nephrectomies were performed: 471 were laparoscopic, two of which were converted from laparoscopic to open and hand-assisted nephrectomy, respectively, and one (.2%) underwent primary open nephrectomy. The mean warm ischemia time was 2.8 min (±1.3 SD, median 3 min, range 2-8 min) and the mean length of stay (LOS) was 4.1 days (±1.0 SD). The mean renal function on discharge was 103 µmol/L (±23.0 SD). Seventy-seven (16%) patients had a complication with no Clavien Dindo IV or V complications seen. Outcomes demonstrated no impact of donor age, gender, kidney side, relationship to the recipient, vascular complexity; or surgeon experience, on complication rate or LOS. CONCLUSION: Laparoscopic donor nephrectomy is a safe and effective procedure with minimal morbidity and no mortality in this series.

ABSTRACT

INTRODUCTION: The purpose of this study was to report our centre's experience using selective angioembolisation in the treatment of iatrogenic renal artery pseudoaneurysms (RAP) following minimally invasive urological procedures. METHODS: Our retrospective analysis included four consecutive patients treated with angioembolisation for iatrogenic RAP between October 2016 and October 2021. Data on demographics, minimally invasive urological intervention, clinical features, imaging findings, embolization procedure and perioperative details were collected. Rates of technical and clinical success, defined as 1. total occlusion of the extravasation site on completion digital subtraction angiography (DSA), and 2. resolution of symptoms, signs, and serum hemoglobin (Hb) derangements secondary to RAP, were analysed. Renal function, measured by serum creatinine (Cr) and estimated glomerular filtration rate (eGFR), was recorded prior to and post - angioembolisation procedure and compared. RESULTS: Mean time between urological intervention and angioembolisation was 9 days (range, 2-17 days). Rates of technical and clinical success were 100% and 100% respectively. No additional angioembolisation procedures were required, and there were no peri or post-operative complications identified during mean follow-up of 662 days (range, 30-1845 days). Mean serum Cr prior to and post angioembolisation was 83 mmol/L and 79.5 mmol/L. Mean eGFR prior to and post angioembolisation was 73.8 and 77.8 mL/min/1.73 m2. In all patients, no significant difference was observed in serum Cr and eGFR prior to and post angioembolisation. CONCLUSION: Iatrogenic renal artery pseudoaneurysms can occur following a range of minimally invasive urological procedures. This retrospective review highlights the utility of angioembolisation as a safe and effective treatment with high clinical and technical success rates. Further studies involving larger populations are required to validate its broader application.

ABSTRACT

Upper tract urothelial carcinoma represents a small proportion (5%-10%) of all urothelial cancers. Although there are several management options, in undifferentiated or high-risk cases, surgery in the form of nephroureterectomy is the gold standard. Horseshoe kidney is the most common congenital renal fusion anomaly affecting 1 in 400-600 patients. We present the case of a smoker in her mid-50s with an incidental finding of a papillary lesion in the right renal pelvis of her horseshoe kidney on CT scan. She went on to have endoscopic assessment confirming no other foci of disease. She was definitively managed with a robotic nephroureterectomy.

ABSTRACT

Iliac artery aneurysms (IAA) are associated frequently with abdominal aortic (AAA) and other degenerative large-vessel aneurysms. Concurrent fistulization of the aortoiliac tree into the gastrointestinal tract (GIT) and bladder is exceptionally rare. We herewith report a unique case of concurrent ilio-enteric and ilio-vesical fistula arising from a large aorto-iliac aneurysm.

ABSTRACT

A premenopausal patient in her late forties presented with a 15-year history of urinary incontinence starting shortly after a caesarean section performed for her fourth delivery and more recently associated episodic light haematuria and passage of clots per vagina. The haematuria was intermittent over several months and associated with per-vaginal bleeding. She had symptomatic anaemia. Flexible cystoscopy and MRI showed a vesicouterine fistula. She underwent a robotic-assisted hysterectomy and multi-layered repair of the bladder with omental interposition. She remained in the hospital for 4 days, though recovered well and underwent catheter removal at 14 days following a normal cystogram. At 3 months, she was well with no incontinence or urinary symptoms. This case demonstrates the need for vigilance in assessing patients with persistent incontinence, particularly in the context of prior caesarean section. It highlights the feasibility of robotic surgery for correcting these defects in a society where minimally invasive surgery is becoming the norm, and cosmesis is a priority for patients.

ABSTRACT

Malakoplakia is a chronic inflammatory condition that affects multiple systems, most commonly the urogenital tract. Its clinical presentation is often non-specific, but is typically characterized by recurrent urinary tract infections and haematuria. We report a rare case of intravesical malakoplakia mimicking an aggressive transitional cell carcinoma both in its clinical presentation and in its macroscopic appearance on cystoscopy in an 82-year patient, the oldest reported case in the literature. Malakoplakia has been described in the literature as a benign disease process presenting typically in younger patients. This case demonstrates its ability to cause obstructive uropathy and affect elderly patients. Thus, this case serves as a reminder to consider malakoplakia as a differential in the evaluation of suspected bladder malignancy in patients of all ages.

ABSTRACT

Presented here is the case of an 86-year-old man who was found to have right-sided pelvicalyceal rupture and anuric renal failure, secondary to obstructive uropathy caused by life-saving extraperitoneal pelvic packing (EPP) in the settling of severe trauma. In efforts to control haemorrhage in this haemodynamically unstable patient, EPP placement deviated from the recognised method of three extraperitoneal packs bilaterally with seven surgical packs placed. Progress postoperative imaging revealed right-sided hydroureteronephrosis with obstruction evident at the level of the extraperitoneal pelvic packs, identified by delayed contrast excretion from the preceding CT angiography imaging. Urology performed bilateral retrograde pyelograms at his relook laparotomy, timed after removal of his extraperitoneal packs and haemostasis, which showed impression of the surgical pack on the distal ureter but no persisting obstruction or short-term complications. Anuric renal failure improved, and renal function returned to near premorbid levels on day 4 postoperatively.

ABSTRACT

We report the first documented case of malignant melanoma obstructing ureters of both moieties of a duplex kidney and contralateral single moiety ureter in a 51-year-old male. The patient presented with fever, coryzal symptoms, and liver function test derangement several years after 2 superficial spreading melanomas were excised with clear margins. Ultrasonography demonstrated hydronephroureter in both moieties of a complete right-sided duplex kidney. Retrograde pyelograms showed bilateral hydronephroureter and filling defects in all 3 ureters. Biopsied tumor cells were positive for S100, Melan A, and HMB45. Cutaneous melanoma metastasizing to ureters is a rare phenomenon and can present a diagnostic challenge to clinicians if clinically silent.

ABSTRACT

BACKGROUND: Total cystectomy and subsequent reconstruction of the urinary tract may be required for primary malignancy of the bladder, or in the context of multi-visceral resection for more advanced pelvic tumors. Complications following urinary diversion are a major source of morbidity, particularly in pelvic exenteration (PE) patients. METHODS: All patients who underwent radical cystectomy alone or during PE at a single tertiary referral centre between 2008 and 2014 were reviewed. Postoperative urological complications were collected and compared between groups. RESULTS: Two hundred and thirty-one patients underwent en bloc cystectomy (98 cystectomy alone, 133 as part of a PE). Postoperative urological complications occurred in 33% of the cystectomy alone group and 59% of the PE group (P < 0.001). PE for recurrence had higher complications than PE for primary malignancy (67% vs. 48%, P = 0.035). Urological leaks occurred in 3%, 6%, and 14% of patient who had cystectomy alone, PE for primary malignancy and PE for recurrence. Major blood loss and previous pelvic radiotherapy independently predicted conduit-associated complications in PE patients (P = 0.002 and 0.035). CONCLUSIONS: Urological complications of cystectomy, particularly urine leaks and sepsis, are more common in patients undergoing PE compared to those with cystectomy alone. Prior pelvic radiotherapy, the extent of surgical resection and major blood loss may contribute to urological morbidity. J. Surg. Oncol. 2017;115:307-311. © 2016 Wiley Periodicals, Inc.
