Lich-Gregoir technique and routine use of double J catheter as the best combination to avoid urinary complications in kidney transplantation.

INTRODUCTION: Urinary complications in kidney transplantation cause patient morbidity and can decrease graft survival. Most of the complications stem from the vesicoureteric anastomosis. Different techniques for ureteroneocystostomy (UNC) have been designed to avoid these complications. The routine use of a double J catheter after the anastomosis has the same purpose. Our aim was to show our experience and compare the use or non-use of a double J catheter and different techniques for ureteric reimplantation with the rate of urologic complications. MATERIAL AND METHODS: We conducted a retrospective, nonrandomized study of 1011 renal transplantations performed between July 1985 and April 2012. We recorded the surgical techniques for UNC, the use or non-use of a double J catheter, and urinary complications (ureteric fistulae and strictures). The first 700 kidney transplantations (group A) were performed using several UNC techniques (Taguchi, Leadbetter-Politano, and Lich-Gregoir) with a selective use of double J catheter according to the criteria of the surgeon. In the last 311 patients (group B), a surgical technique was established (Lich-Gregoir), as well as the universal use of double J catheters. RESULTS: Urinary fistula occurred in 7% of group A patients and 2% of group B patients (P = .0001). Ureteric stricture occurred in 5.3% of patients in group A and 3% of group B patients (P = .09). In our study, routine prophylactic stenting combined with the Lich-Gregoir UNC technique has decreased the incidence of postoperative fistulae. CONCLUSIONS: Individually, the use of double J catheters seems to lessen the incidence of fistulae, although statistically, the difference is not significant. Accurate knowledge of the complications rates, recommendations of guidelines, and the early diagnosis are essential to attaining reasonable results in kidney transplantation.

[Morbidity and risk factors of transrectal prostate biopsy]. / Morbilidad y factores de riesgo de la biopsia transrectal prostática.

OBJECTIVES: To evaluate the incidence of minor complications that rarely need treatment (haematuria, hematospermia and rectal bleeding) and major complications (fever and shock) in patients undergoing transrectal biopsy of the prostate and to identify risk factors. PATIENTS AND METHODS: We present an analytic and prospective study where we evaluated 146 patients subjected to transrectal biopsy of the prostate from December 2007 to September 2008. Complications rates and variables were analyzed. RESULTS: Eight patients (5,5%) suffered fever and seven (4,8%) of them were admitted. One of the patients (0,7%) suffered shock. The median of time between biopsy and fever was 3.5 days (1-10 days). Haematuria and hematospermia were more frequent in patients younger than 65 years (p<0.05) and fever and sepsis were more frequent in patients with prostate volume smaller than 55mL (p<0.05). CONCLUSIONS: The complications of the transrectal biopsy of the prostate are frequent, autolimited and they rarely suppose a health hazard for the patients. The most frequent are haematuria and hemospermia, specially in younger patients, whereas infectious complications are rarer and in our study are more frequent in patients with smaller prostates. We must take into account that the information to the patient is very important after a prostate biopsy, so we can avoid useless consultations (for example with haematuria) and it will enable to identify important signs like fever earlier.

[Hand-assisted laparoscopic nephrectomy in challenging cases]. / Nefrectomía laparoscópica asistida por la mano en casos difíciles.

OBJECTIVE: To assess the outcome of hand-assisted laparoscopic nephrectomy in patients with significant complicating clinical factors. METHODS: A retrospective assessment was made of 100 laparoscopic nephrectomies performed at a single hospital from 2001 to 2005. Patients with a history of prior abdominal surgery, prior procedures on the involved kidney, evidence of perirenal inflammation, renal lesions 10 cm or more in diameter, or level I renal vein thrombosis were enrolled. RESULTS: Twelve patients were enrolled. Of these, 5 had a lesion at least 10 cm in diameter, 2 had renal vein thrombosis, and 5 reported major abdominal surgery. Most patients had more than one of these findings. Three patients showed inflammatory conditions (staghorn calculi) and a T4 renal tumor was successfully treated without conversion to open surgery. Mean operating time and blood loss were 210 minutes and 310 ml respectively, while mean length of hospital stay was 3 days. No patient required conversion to open surgery. CONCLUSIONS: Hand-assisted laparoscopic nephrectomy is an attractive minimally invasive option for technically challenging tumors and has reasonable operating times, blood losses, and complication rates.

[Does cystocele have a role in bladder outlet obstruction]. / ¿Es realmente el cistocele un factor de obstrucción infravesical?

INTRODUCTION: Controversy exists as to whether cystocele has a causative role in bladder outlet obstruction (BOO). OBJECTIVE: To assess the relationship between cystocele and bladder outlet obstruction. MATERIALS AND METHODS: Two hundred women undergoing a urodynamic study from December 2007 to December 2008 were retrospectively assessed. Patients were divided into two groups: Group A: Patients with no cystocele (Grade 0) and Grade I cystocele Group B: Patients with Grade II-IV cystocele. EXCLUSION CRITERIA: 1. Absence of flowmetry or voided volume < 150 ml. 2. Neurological disorders. 3. History of urogenital surgery. Bladder outlet obstruction was defined as follows: Postvoid residue (PVR) > 20%; peak flow (Qmax) < 15 ml/sec; detrusor pressure at maximum flow (PdetQmax) > 25 cm H2O. RESULTS: Group A included 64% of patients, and Group B the remaining 36%. A pathological PVR > 20% was found in 26.6% and 40.3% of patients in Group A and Group B respectively (p=0.04). A Qmax < 15 mL/sec was seen in 15.6% and 27.8% of Group A and Group B patients respectively (p=0.03). A PdetQmax > 25 cm H2O was found in 26.3% and 47.8% of Group A and Group B patients respectively (p=0.01). CONCLUSIONS: A statistically significant association exists between cystocele and bladder outlet obstruction.

Nefrectomía laparoscópica asistida por la mano en casos difíciles / Hand-assisted laparoscopic nephrectomy in challenging cases

Objetivo: evaluar los resultados de nefrectomía laparoscópica asistida por la mano en pacientes con masas renales técnicamente complejas. Métodos: se ha realizado una evaluación retrospectiva de 100 nefrectomías laparoscópicas realizadas en un solo hospital entre 2001 y 2005. Se ha seleccionado a los pacientes con antecedentes de cirugía abdominal previa, procedimientos previos en el riñón afectado, evidencia de inflamación perirrenal, lesiones renales de más de 10 cm de diámetro o trombosis venosa renal tipo I. Resultados: se ha incluido un total de 12 pacientes; 5 de ellos presentaban una lesión de al menos 10 cm de diámetro, dos trombosis venosa renal y 5 referían cirugía abdominal mayor. La mayoría de los pacientes tenía más de uno de estos hallazgos. Tres pacientes presentaban procesos inflamatorios (cálculos coraliformes) y un tumor renal T4 fue tratado con éxito, sin necesidad de reconversión. El tiempo operatorio y la pérdida sanguínea medias fueron de 210 minutos y 310 ml, respectivamente, con una estancia media de tres días. Ningún paciente requirió reconversión a cirugía abierta. Conclusiones: la nefrectomía laparoscópica asistida por la mano es una opción mínimamente invasiva, atractiva en el contexto de masas técnicamente complejas, con un tiempo operatorio, una pérdida sanguínea y una tasa de complicaciones razonables (AU)
