INTRODUCTION: A pelvic lymphocele is a collection of lymphatic fluid that develops after extensive lymphadenectomies in surgeries such as urological malignancies or renal transplantation. Pelvic lymphoceles may cause complications such as fever, abdominal pain, leg swelling, genital swelling and flank pain. This report summarizes the management of a pelvic lymphocele after open radical retropubic prostatectomy with bilateral lymphadenectomy. PRESENTATION OF CASE: Herein, we present a case in which a pelvic lymphocele developed seven months post-radical open retropubic prostatectomy and through this patient we discussed the lymphocele following radical prostatectomy...

Allograft lithiasis is a rare urologic complication of renal transplantation (RT). Our aim is to present our experience with minimally invasive surgical treatment of allograft lithiasis in our series of live-donor renal transplant recipients. In a retrospective analysis of 3758 consecutive live-donor RTs performed in our center between November 2009 and January 2017, the results of minimally invasive surgery for the treatment of renal graft lithiasis diagnosed at follow-up were evaluated. Twenty-two (0.58%) patients underwent minimally invasive surgery for renal graft lithiasis...

We aimed to evaluate the influence of urological complications occurring within the first year after kidney transplantation on long-term patient and graft outcomes, and sought to examine the impact of the management approach of ureteral strictures on long-term graft function. We collected data on urological complications occurring within the first-year post-transplant. Graft survivals, patient survival, and rejection rates were compared between recipients with and without urological complications. Male gender of the recipient, delayed graft function, donor age were found to be significant risk factors for urological complications after kidney transplantation (p<0...

Although they are not common, urologic complications after renal transplant are associated with risk of graft loss. Fluid collection during the postoperative period can be caused by urine leak or lymph leak of seroma. Biochemical analysis of the drained liquid is essential and should be compared with a concomitant serum sample. Surgical exploration is indicated if suspected urine leak is significant. Reimplantation of the ureter to the bladder can be challenging if there is extensive ureteral necrosis due to compromised vascularization...

BACKGROUND: The external iliac vein is the standard site used for venous anastomosis in kidney transplantation. When a pre-transplantation diagnosis of iliocaval thrombosis is established, a different and suitable venous drainage for the renal outflow must be identified for successful transplant. METHODS: We report 4 cases of kidney transplantation, performed from 2004 to 2016, in recipients presenting with thrombosis of the inferior vena cava and iliac system needing, because of the lack of access for dialysis, urgent kidney transplantations...

PURPOSE OF REVIEW: The techniques derived from abdominal transplant surgery have become a major actor in recent surgical evolution by providing a more optimal solution for urologic malignancies hosted in the upper abdomen. To describe in detail the objectives, rationale, relevant milestones, and surgical maneuvers of the so-called transplant techniques as applied to complex urologic oncology cases. RECENT FINDINGS: The transplant-based surgical approach aims to decrease perioperative complications by improving tumor accessibility and field visibility through an enhanced exposure (via the use of a transverse incision, a specific retractor, and specific surgical maneuvers)...

PURPOSE OF REVIEW: The practice of kidney autotransplantation (KAT) has become an increasingly favorable approach in the treatment of certain renovascular, ureteral, and malignant pathologies. Current KAT literature describes conventional open procedures, which are associated with substantial risks. We sought to compare previously reported outcomes, evaluate common surgical indications, and assess associated risks and benefits of current KAT methods. A thorough evaluation and review of the literature was performed with the keywords "autologous transplantation" and "kidney...

BACKGROUND: Clinicians use several diagnostic modalities to recognize post-transplant complications, such as acute tubular necrosis, acute rejection, urologic and vascular complications. Currently, there is no consensus about the best procedural approach to evaluate post-transplant renal dysfunction. Renal needle-biopsy is often required, however, this is invasive and may lead to sample errors and complications, and most clinicians prefer using one of the noninvasive diagnostic modalities...

Background: Percutaneous nephrolithotomy (PCNL) is a procedure typically performed under general anesthesia (GA); however, many patients might be considered unfit for GA and locoregional anesthesia is their only chance to have the procedure done. Case Presentation: A 60-year-old Middle-Eastern female with end-stage lung disease underwent evaluation for lung transplant; she was found to have severe restrictive pattern on steroid and continuous oxygen therapy, pulmonary hypertension with dilated right ventricle, chronic anemia, and asthma...

BACKGROUND: Kidney transplantation is the treatment of choice for patients with end-stage kidney disease. In a previous review we concluded that the routine use of ureteric stents in kidney transplantation reduces the incidence of major urological complications (MUC). Unfortunately, this reduction appears to lead to a concomitant rise in urinary tract infections (UTI). For kidney recipients UTI is now the commonest post-transplant complication. This represents a considerable risk to the immunosuppressed transplant recipient, particularly in the era of increased immunologically challenging transplants...

BACKGROUND: Although several risk factors for erectile dysfunction may be present in patients with cirrhosis, data on the actual prevalence and cause of erectile dysfunction is limited. The International Index of Erectile Function-5 (IIEF-5) is a well-validated survey to determine the presence and severity of erectile dysfunction in men. We assessed (i) the prevalence and severity of erectile dysfunction, and (ii) risk factors for erectile dysfunction in patients with cirrhosis. METHODS: In this prospective study, erectile dysfunction was defined as: absent (>21 IIEF-5-points), mild (12-21) and severe (5-11)...

Ureteral stents are routinely used in renal transplant and are associated with reduced urological complications but increased urinary tract infections (UTIs). There is no agreement on the preferred time to removal of stents after transplantation. We performed a systematic review and meta-analysis of all randomized controlled trials (RCTs) comparing stent duration of <14 days vs > =14 days. Electronic databases were searched to identify RCTs that compared early vs late stent removal. Primary outcome was urinary tract infections...
