Papillary Renal Cell Carcinoma in Lynch/Muir-Torre Syndrome with Germline Pathogenic Variant in and Molecular Analysis: Report of a Case and Review of the Literature.

J Kidney Cancer VHL 2021 21;8(2):8-19. Epub 2021 Apr 21.

Department of Pathology & Immunology.

Lynch syndrome (LS) is an autosomal dominant inherited disorder due to pathogenic variations in the mismatch repair genes, which predisposes to malignancies, most commonly colon and endometrial carcinoma. Muir-Torre syndrome is a subset of LS with cutaneous sebaceous adenoma and keratoacanthoma in addition to the malignancies. Renal cell carcinoma (RCC) in patients with LS is extremely rare.

Robot-Assisted Laparoscopic Partial Nephrectomy for Allograft Renal Cell Carcinoma: A Case Report.

Transplant Proc 2021 May 4. Epub 2021 May 4.

Department of Urology, Tokyo Women's Medical University, Shinjuku-ku, Tokyo, Japan.

Background: Nephron-sparing surgery is required for patients with kidney transplant with organ-confined renal cell carcinoma (RCC) in the allograft kidney to preserve renal function. Robot-assisted laparoscopic partial nephrectomy (RAPN) is expected to be the optimal surgical approach for these patients, as in the general population. However, RAPN for RCC arising in the allograft kidney is rarely reported. Read More

Mol Clin Oncol 2021 Jun 23;14(6):109. Epub 2021 Mar 23.

Department of Urology, Lourdes Clinic, I-80040 Massa di Somma, Italy.

Multilocular cystic nephroma is a rare benign kidney tumor, which is typically characterized by a unilateral, multicystic renal mass without solid elements. Cystic nephroma has a bimodal distribution and two-thirds of tumors involve children aged between 3 months and 2 years, with male predominance; a second peak affects the age group >30 years old, in which females are predominantly affected. The incidence rate for this rare tumor in patients aged 5-30 years is only 5%. Read More

Can extended upper pole ureterectomy prevent ureteral stump syndrome after proximal approach for duplex kidneys?

Int Braz J Urol 2021 Jul-Aug;47(4):821-826

Unidade de Urologia Pediátrica, Divisão de Urologia, Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo - FMUSP, SP, Brasil.

Introduction: Symptomatic duplex kidneys usually present with recurrent urinary tract infection due to ureteral obstruction (megaureter, ureterocele or ectopic ureter) and/or vesicoureteral reflux. Upper-pole nephrectomy is a widely accepted procedure to correct symptomatic duplex systems with poor functioning moieties, also known as upper or proximal approach. The distal ureteral stump syndrome (DUSS) can be a late complication of this approach. Read More

Pathologically diagnosed incidentaloma transition cell carcinoma (TCC) of renal pelvis in a laproscopic radical nephrectomy specimen done for a lower pole renal mass.

Urol Case Rep 2021 Jul 11;37:101607. Epub 2021 Feb 11.

Apollo Hospitals, Indore, India.

We are reporting a very rare case in the current era of modern diagnostics of an incidentally detected Transitional Cell Carcinoma(TCC) renal pelvis, detected pathologically when Right laparoscopic radical nephrectomy specimen of lower pole mass(RCC) was processed, with no prior suspicion of TCC clinically or pre-operative imaging. A 75-year-old female with 4 × 4cm strongly enhancing lower pole renal mass on CTscan underwent a Laparoscopic Radical Nephrectomy. Surprisingly histopathological examination revealed a focus of low-grade TCC, arising from renal pelvis, completely separate from lower pole mass which was a clear cell RCC. Read More

A Case Series of Delayed Proximal Ureteral Strictures After Nephron-Sparing Treatment of Renal Masses.

J Endourol Case Rep 2020 29;6(4):544-547. Epub 2020 Dec 29.

Division of Urology, Department of Surgery, Washington University School of Medicine, St. Louis, Missouri, USA.

Delayed proximal ureteral stricture (DPUS) after nephron-sparing treatment (partial nephrectomy [PN] and image-guided percutaneous ablation) of renal masses is a rare complication that occurs because of an unrecognized injury to the proximal ureter and/or its associated vascular supply. We present a multi-institutional series of patients who developed DPUS after nephron-sparing treatment and review relevant tumor characteristics, timing of DPUS presentation, presenting symptoms, and outcome of stricture management. Between 2000 and 2019, nine patients (five PN and four ablation) were found to have DPUS diagnosed at an average of 9 (6-119) months after PN and 5. Read More

Laparoscopic ligation of ectopic ureter in pediatric patients: a safe surgical option for the management of urinary incontinence due to ectopic ureters.

Pediatr Surg Int 2021 May 15;37(5):667-671. Epub 2021 Jan 15.

Division of Pediatric General Surgery, Department of Surgery, University of Manitoba, 820 Sherbrook Street, Winnipeg, MB, R3A 1R9, Canada.

Background: Ureteric ectopia is a pediatric urinary incontinence cause in girls. It is traditionally managed through hemi-nephrectomy or uretero-ureterostomy, which have the potential for complications including anastomotic stricture, leak, bleeding, and de-vascularization of the functioning renal moiety. Laparoscopic ureteric clipping has been shown to be a good alternative but has not been widely adopted yet. Read More

Complex Surgical Reconstruction of Upper Pole Artery in Living-Donor Kidney Transplantation.

Ann Transplant 2021 Jan 15;26:e926850. Epub 2021 Jan 15.

Department of Surgery, Miami Transplant Institute, Miami, FL, USA.

BACKGROUND The use of allografts with multiple renal arteries has increased in the era of laparoscopic donor nephrectomy. Although several studies recommend reconstructing lower pole arteries (LPAs) to reduce risk of urologic complications, it is common opinion to ligate upper pole arteries (UPAs) with a diameter less than 2 mm because of increased risk of thrombosis related to their reconstruction. This retrospective study evaluates the feasibility and safety of reconstructing thin UPAs during living-donor kidney transplantation, with the goal of maintaining the integrity of the graft and assuring its maximal function.

Adrenal-Renal Fusion with Adrenal Cortical Adenoma and Ectopic Adrenal Tissue, Presenting as Suspected Renal Mass: A Case Report.

Curr Urol 2020 Oct 13;14(3):163-165. Epub 2020 Oct 13.

Division of Urology, Department of Surgery, St Louis, MO, USA.

Adrenal-renal fusion with adrenal cortical adenoma is a rare anomaly with only a few cases described in the literature. Imaging-based identification of this anomaly remains a diagnostic challenge, making it difficult to differentiate upper pole renal malignancy from adrenal cortical adenoma. We describe a case of a 62-year-old woman with an upper pole cystic renal mass on imaging, who underwent robotic partial nephrectomy. Read More

Usage of Modified Makuuchi Incision for Surgical Management of Complex Renal and Adrenal Lesions.

Cureus 2020 Oct 18;12(10):e11012. Epub 2020 Oct 18.

Surgical Gastroenterology, Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Puducherry, IND.

Background:  Modified Makuuchi (MM) incision is less popular among the urological fraternity as Chevron, subcostal, flank, and midline incisions are commonly used for most of the complex renal and adrenal conditions.
