Needlescopic surgery for cryptorchidism: the initial series

Undescended Testes and Laparoscopy: Experience from the Developing World

Background

Cryptorchidism or undescended testes is the most common disorder of the male endocrine glands in children. With the advancements in laparoscopic techniques and instruments, laparoscopic orchidopexy has become the standard procedure in the management of nonpalpable undescended testes.

Aim

To evaluate and determine the therapeutic role, sensitivity, and specificity of laparoscopy in localizing nonpalpable testes and the mean operative time, the conversion rate (and reasons thereof), postoperative wound infection, postoperative stay, and time taken for return to daily activities following laparoscopic orchidopexy or orchidectomy.

Materials and Methods

This was a prospective study carried out in the Postgraduate Department of Surgery, Government Medical College, Srinagar, J&K, India, from May 2008 to August 2011. All patients who presented to the outpatient department with complaints of absent testes were examined, and the ones with nonpalpable testes were included in the study.

Results

The mean operative time for bilateral and unilateral nonpalpable testis was 102.76 and 53.67 minutes, respectively. Minor postoperative wound infections were noted in 4 of our patients. Mean duration of hospital stay was 14.23 hrs for unilateral cases and 16.27 hrs for bilateral cases. Patients who underwent laparoscopic orchidopexy resumed their normal activities within 4 ± 1 days.

Conclusion

Laparoscopy clearly demonstrates the anatomy and provides visual information upon which a definitive decision can be made for further management of the undescended nonpalpable testis.

Mini-laparoscopic live donor nephrectomy with the use of 3-mm instruments and laparoscope

PURPOSE

To analyze our preliminary outcomes on the use of 3 mm instruments for laparoscopic live donor nephrectomy (LLDN).

METHODS

Our series includes thirteen patients, who underwent LLDN using 3-mm instruments and laparoscope and 5-mm transumbilical trocar. The patients were followed at 7 and 14 days from discharge and were specifically asked about their cosmetic satisfaction. At follow-up, the recipient graft function was controlled, as well as the donor's cosmetic results. Eight months after surgery, all thirteen patients were asked to fill out the Patient Scar Assessment Questionnaire and Scoring System (PSAQ).

RESULTS

All patients presented good recovery after surgery. Regarding cosmetic outcomes, the donors expressed their satisfaction toward the minimal incision size and optimal esthetic results at 7 and 14 days from discharge home. The low scores on each section of the PSAQ confirmed the favorable outcomes. Early graft function was satisfactory at 1 and 3 months after the kidney transplantation. Furthermore, there were no major complications in the recipients.

CONCLUSIONS

Our persistent positive results with the use of 3-mm instruments during LLDN support this technique as a good alternative to the standard laparoscopic approach for minimizing the incision site, while maintaining safety and excellent clinical outcomes. The fact that the general laparoscopic standards are maintained could make this approach a very attractive alternative to the other minimally invasive approaches for live donor nephrectomy. The hope is in that the higher degree of satisfaction in the donor population demonstrated in this study may likely enhance living kidney donation.

Minilaparoscopy and laparoendoscopic single-site surgery: mini- and single-scar in urology

PURPOSE

To review the development of laparoscopic single-site surgery (LESS) and minilaparoscopy (ML), with particular attention to the urological field, focusing on nomenclature, history and outcomes.

METHODS

A literature search was conducted on laparoendoscopic single-site surgery, minilaparoscopy, needlescopy and microlaparoscopy. The most relevant papers were selected over the last 30 years.

RESULTS

830 manuscripts were found about LESS, 251 in urology, two CRTs and nine match-case controls. 258 papers were about ML and 55 in urology. ML is the main topic (169 papers), followed by needlescopy (58) and microlaparoscopy (32). The most significant articles are four non-randomized match-case control studies.

CONCLUSIONS

Over the last few years, many urological laparoscopic operations have been successfully performed by LESS. However, the actual role of LESS remains to be determined with controversial data about postoperative pain control and almost no results on cosmesis. We are facing second-generation ML with superior performance granted by new endoscopes and most effective instruments. ML has demonstrated in almost all urologic indications to be feasible, safe and able to improve cosmetic and postoperative pain control. Anyway, CRTs are still lacking and only studies from other discipline can corroborate this trend.

Laparoscopic live donor nephrectomy with the use of 3-mm instruments and laparoscope: initial experience at a tertiary center

Laparoscopy has become the standard of care for kidney recovery during live donor nephrectomy (LDN) because of the well-documented better outcomes of minimally invasive surgery compared with the open approach. Especially in the donor population, the cosmetic results are of great importance; therefore, an effort to reduce the incision size should be attempted while maintaining the safe general principles of surgery. We present our initial experience with the use of 3-mm instruments for laparoscopic LDN.

Early insertion of trans-scrotal port during laparoscopic orchidopexy: a new concept

Laparoscopic orchidopexy has become the routine tool in managing abdominal testes. Many techniques have been used to deliver the dissected testis to the scrotal position; a trans-scrotal port is one of them. We present a technique in which the trans-scrotal port is inserted early on, and used not only for testis delivery but also to aid the testicular dissection. We used the technique for 15 abdominal testes in 13 boys and it was safe, and very helpful in dissecting the vascular pedicle to higher levels in an ergonomically easier plane. In addition, it helped in establishing the tract and eventually guiding the dissected testis to the desired scrotal position (12 low and 3 mid-scrotal).

Laparoscopy for impalpable testis: classification-based management

BACKGROUND

The undescended testis represents one of the most common disorders of childhood. The authors evaluated the safety and efficacy of laparoscopy for the abdominal testis and present a classification of the laparoscopic diagnostic findings to facilitate decision making.

METHODS

Between 2000 and 2005, 95 patients (22 bilateral and 73 unilateral testes, for a total of 117 impalpable testes) with a mean age of 5 years underwent laparoscopy. The testis was managed according to a special classification of the diagnostic findings. Testicular position, size, and viability according to technetium-99m ((99m)Tc) were assessed during the follow-up evaluation.

RESULTS

The laparoscopic findings were classified into six types: type 0 (no testis or vanished testis proximal to the internal ring; 9 patients [7.5%]); type 1 (atrophic intracanalicular testis; 6 patients [5.4%], for whom no further intervention was administered); type 2 (testis at the internal ring with looping vas; 15 patients [14.5%], for whom laparoscopic orchiopexy was performed); type 3 (testis at the internal ring without looping of the vas; 29 patients [24.7%], for whom laparoscopic orchiopexy also was performed; type 4 (high abdominal testes; 49 patients [41.9%], with Staged Fowler-Stephens orchiopexy performed for 47 testes and laparoscopic orchidectomy for 2 testes; and type 5 (persistence of Müllerian duct structures [PMDS] or other abnormalities; 7 testes [6%]). After a mean follow-up period of 3 years, the laparoscopic orchiopexy testes were of good size and viable, but four testes (8.7%) were at the neck of the scrotum. The laparoscopically staged Fowler-Stephens orchiopexy group showed atrophy in two testes (4.3%), and all were in the bottom of the scrotum.

CONCLUSIONS

Classification of the laparoscopic findings facilitates decision making. Laparoscopic orchiopexy is a natural extension of diagnostic laparoscopy for the intraabdominal testis at the internal ring or that seen peeping from it. Laparoscopically staged Fowler-Stephens orchiopexy is the procedure of choice for the high intraabdominal testis not amenable to the one-stage procedure.

Microlaparoscopy

Laparoscopic surgeons have made significant efforts to minimize the trauma induced by their procedures. One of the newest methods is the use of mini and micro instruments. This work is reviewed here.

Laparoscopic Reconstructive Urology

PURPOSE

Although laparoscopy has emerged as a feasible and effective alternative for a majority of open ablative abdominopelvic urological procedures, minimally invasive reconstruction has come to the forefront only recently. We present the current state of the art of laparoscopic reconstructive urology.

MATERIALS AND METHODS

We conducted an extensive MEDLINE search of purely laparoscopic surgery from 1976 through 2002. Based on the results, we divide clinical reconstructive laparoscopic procedures into 2 broad categories-established and evolving. Each category is further classified according to the organ involved-adrenal and kidney, ureter (evolving only), bladder and prostate, and miscellaneous. Clinical procedures were considered established if our literature review revealed any report of more than 100 patients, or reports from at least 5 different centers greater than 20 patients each. If these criteria were not met, the procedure was considered clinically evolving.

RESULTS

Laparoscopic reconstructive procedures such as pyeloplasty, radical prostatectomy and orchiopexy have achieved clinically established status. Laparoscopic bladder neck suspension, although reported in a significant number of cases, remains controversial because of its contradictory reported long-term success rates. Multiple additional laparoscopic reconstructive procedures have been performed in fewer numbers clinically with promising results.

CONCLUSIONS

Until recently, urological laparoscopic surgery primarily focused on ablative procedures, with success. Building on this initial experience, advanced and sophisticated reconstructive procedures of considerable technical complexity are increasingly being performed purely laparoscopically. It is anticipated that in the future laparoscopic surgery could increasingly evolve into a preferred approach for advanced and sophisticated urological reconstruction.

New surgical techniques in pediatric urology

More sophisticated endoscopic instruments, combined with a better understanding of bladder and urethral pathology, have significantly improved the therapeutic approaches for both posterior urethral valves and ureteroceles. New generation lithotripters have allowed for a safe and efficient method of treating urinary calculi in children, which was once thought too injurious a process with first-generation machines. The rapidly advancing field of laparoscopy, aided by the development of more optically refined and diminutive instruments, has allowed for its application in a wide variety of surgical interventions in pediatric urology. The tubularized incised plate urethroplasty has challenged more traditional approaches to hypospadias repair and is now considered by many pediatric urologists to be the best approach for midshaft and distal hypospadias. The one-stage approach to exstrophy repair may hold the answer to improved continence without a formal bladder neck reconstruction. Finally, the field of tissue engineering leads the way to new advances in autologous biological substitutes in the surgically-challenged patient where there is a shortage of local tissues at the surgeon's disposal.

Needlescopic urology: current status

Technological miniaturization is an emerging trend that encompasses virtually all surgical subspecialties. Minimization of surgical trauma while maximizing surgical cure through gradual progression from maximally invasive to minimally invasive to ultimately noninvasive technologies must be the goal. Needlescopic techniques represent a natural evolution and sophistication of conventional laparoscopy. At the author's center, needlescopic techniques have been used to particular advantage in four specific clinical applications: adrenalectomy, pediatric orchiopexy, detaching the bladder cuff during laparoscopic nephroureterectomy, and as an adjunctive needlescopic port for retraction purposes during conventional laparoscopic surgery. Given the urologist's natural facility with small-diameter endoscopes, the specialty is uniquely positioned to take a leadership position in this emerging field. Increased experience and careful comparisons with conventional laparoscopy will determine the true role of needlescopic technology in the armamentarium of the urologic surgeon.
