Supine mini percutaneous nephrolithotomy in horseshoe kidney.

Objective: The percutaneous nephrolithotomy (PCNL) in Horseshoe kidneys (HSK) is usually performed in the prone position, allowing entry through the upper pole and providing good access to the collecting system. However, in patients with normal kidney anatomy, the supine position is reliable and safe in most cases, but it is unknown whether the supine position is adequate in patients with HSK. The purpose of this study was to describe the results of PCNL in HSK in three different surgical institutions and to evaluate the impact of supine position during surgery, comparing pre-operative and post-operative data, complications, and stone status after surgery.

Stone free rate and clinical complications in patients submitted to retrograde intrarenal surgery (RIRS): Our experience in 571 consecutive cases.

Introduction: The purpose of this study is to report the stone free rate (SFR) and clinical complications in patients submitted to retrograde intrarenal surgery (RIRS).

Materials And Methods: A total of 571 procedures of upper urinary stones treated using flexible ureteroscopy and holmium laser lithotripsy from January 2014 to February 2020 have been analyzed. Overall SFR was evaluated after 3 months following the procedure by means of a non-contrast computed tomography.

Asynchronous Bilateral Ureteric-Arterial Fistula: Diagnosis and Treatment.

A 48-year-old woman submitted to anterior exenteration plus ileal-cutaneous conduit for metastatic cervical cancer during the change of the ureteral stent showed massive bleeding in the left ureter. A selective intra-arterial angiography showed a fistula between the ureter and the left common iliac artery that the interventional radiologist quickly repaired by inserting a vascular endoprosthesis. Six months later, gross hematuria secondary to right ureter-iliac fistula occurred again and a second endoprosthesis was inserted.

Subcapsular Kidney Urinoma After Percutaneous Nephrolithotomy.

A rare percutaneous nephrolithotomy (PCNL) complication and its management is reported. A male patient, 43 years of age, underwent PCNL for a large left pyelocaliceal stone. Surgery was performed in the Valdivia-Galdakao supine position.

Primary carcinoid tumour of the testis: A case-report.

Testicular carcinoid tumours (TCT) account for less than 1% of all testicular neoplasms. A 17-year-old male underwent radical orchiectomy for a painful indurated and increased in size right testicle; a mixed echogenic mass, with a central homogeneous area surrounded by a hypoechoic edge with calcifications was found at ultreasound with increased vascularity at color Doppler examination. Biochemical markers were within normal limits.

Carcinosarcoma of the Female Urethra.

Carcinosarcoma is a rare malignant tumor with a biphasic morphology characterized by the presence of a malignant epithelial and mesenchymal component. It has been reported in many organs, including the genitourinary tract. We describe a case of a 47-year-old woman admitted to our hospital for history of recurrent urinary tract infection, dysuria and discharge of bloody fluid from the urethra at the end of urination.

Management of severe blunt renal trauma in adult patients: a 10-year retrospective review from an emergency hospital.

Unlabelled: What's known on the subject? and What does the study add? Immediate surgery for major renal truma has led to a high rate of nephrectomy in comparison with an expectant management. We reviewed our case material on the management of severe blunt renal trauma in adults with emphasis on conservative management. Only shattered kidneys and pedicle avulsion required immediate surgery.

Prevalence and clinical significance of prostate cancer among 12,682 men with normal digital rectal examination, low PSA levels (< or =4 ng/ml) and percent free PSA cutoff values of 15 and 20%.

Aim: To report prevalence and clinical relevance of T1c prostate cancers (PCa) in a selected population of men with serum prostate-specific antigen (PSA) levels < or =4 ng/ml enrolled in a multicenter case-finding protocol.

Patients And Methods: A number of 16,298 men, aged 40-75 years, from the urology units they had been referred to, in most cases (81.6%) for lower urinary tract symptoms, were evaluated.

Should men with serum prostate-specific antigen < or =4 ng/ml and normal digital rectal examination undergo a prostate biopsy? A literature review.

The clinical significance of a prostate cancer (PCa) cannot be determined solely by tumor volume (< or =0.5 cm(3)), as small tumors of higher Gleason grade and tumors occurring in younger men may become clinically significant even though the initial volume at diagnosis is small. A certain number of these minimal cancers are likely to remain clinically insignificant; however, it is unpredictable how many can progress beyond the curable stage by the time there is a rise in serum prostate-specific antigen (PSA) values.

Isolated local recurrence of renal neoplasm with caval involvement 16 years after radical nephrectomy.

Objective: To report a case of local recurrence 16 years after radical nephrectomy; to analyse literature data concerning, treatment and prognosis.

Methods/results: We report a case of local recurence associated with caval trombosis who was underwent an en-bloc resection of vena cava along with pericaval lesion and caval replacement with PTFE prosthesis. The Authors reviewed and analysed literature data.

End-to-end ureteral anastomosis: a simple alternative to cutaneous ureterostomy in selected patients.

Unlabelled: End-to-end of terminal ureteral segments seems to be a good alternative to terminal cutaneous ureterostomy in very selected cases (patients with short life-expectancy or when it is impossible to utilize the bowel for urinary diversion).

Background: An end-to-end ureteral anastomosis (UA) drained by a single percutaneous nephrostomy is proposed as an alternative to permanent cutaneous ureterostomy.

Methods: In eight patients who underwent radical cystectomy, an end-to-end UA was realized.

[Unusual case of calcified renal fibroma].

The renal fibroma is an extremely rare event that takes its origin from parenchima, from the peri-renal tissues or from the renal capsule. A case of renal fibroma of a rarely met medullary origin is described.

[Heredity in renal and prostatic neoplasia].

There is an ever growing report of data supporting the evidence that accumulated genetic changes underlie the development of neoplasia. The paradigma of this multistep process is colon cancer were cancer onset is associated, over decades, with at least seven genetic events. The number of genetic alterations increases moving from adenomatous lesions to colon cancer and, although the genetic alterations occur according to a preferred sequence, the total accumulation of changes rather than their sequential order is responsible of tumor biological behavior.
